New mattress for baby no.2 due to SIDS?

I thought we were kind of ready and prepared for baby nr. 2 and then a friend mentioned that you should get a new mattress because you should never use an old mattress for a new baby because of cot death risk.

I have heard this before, have you got new mattresses for each sibling?

No. DSs 1-3 used same mattress, as will DS4 on his arrival [tight emoticon].

You do not need a new mattress for a new baby within the same family.
Any potential bugs are the same.

If you bought a secondhand cot, you should invest in a new mattress.

Glad you posted this Ninni, I'm in the same predicament wondering if I should. I'm due in April with DS number 2.

I've bought a new moses basket mattress but that's because a) we lent moses basket (inc. mattress) to friends after DS1 used it and b) a new mattress only costs a tenner.

I'm not not sure whether or not we should get a new mattress for the pram, and / or for the cot bed that DS2 will go into when he's a couple of months old.

FWIW my SIL told me I should only get new mattresses if DS1 was very 'sicky'. He wasn't sick much at all as a little one but had awful sickness bug when in cot bed and projectiled over the cot bed mattress repeatedly so am now thinking perhaps I ought to buy a new cot bed mattress, just to be on the safe side.

If anyone's got any official advice /statistics I'd love to hear them.

tassisssss · 20/01/2010 21:28

We did, but only because dh insisted, I'm really not convinced.

greensnail · 20/01/2010 21:32

I think I probably will get a new mattress for DC2 (due in June) although I'd heard you don't need to in the same family. We bought the cheapest mattress going for DD thinking we'd only need to replace it for DC2 anyway, so think its only fair to actually replace it now!

DiamondHead · 20/01/2010 21:33

Surely the SIDS website will have some information on this. I never bothered though.

MumNWLondon · 20/01/2010 23:25

i had my cot mattress profesionally cleaned after DD and I will do the same before this baby is born, buying new mattress seems a bit excessive.

meltedchocolate · 20/01/2010 23:31

I dont know if this is relevant but my DS is sleeping in the cot MY MUM (then me and my siblings, then cousins) slept in all those years ago. Same cot, new matress.

displayuntilbestbefore · 20/01/2010 23:31

I got a new mattress for each sibling but only because each mattress had been thoroughly wee-d on, puked on, slobbered on etc and although it obviously didn't always go right through to mattress and we used protectors, kept it clean etc, seeing as we had all the other baby gear dh and I felt it fair on the new baby to at least have a fresh new mattress of their own (it would have been more than unfair on ds3 having one that had already had 2 babies' use!).
I wasn't thinking of SIDS tbh when we did it, more just the comfort aspect of it.

meltedchocolate · 20/01/2010 23:34

Actually no, my post isn't that relevent.

Ninni · 21/01/2010 09:09

It seems matresses covered with PVC are OK if properly cleaned.... will call SIDS today to double check what they say and let you know.

I got a new mattress for the moses basket but not for the actual cot.
I read that you should get a new mattress for each new baby because of the effect the weight of the previous baby would have had on the mattress iyswim.
My mosses basket mattress had a bit of a dip in it from ds1 being in it for 3 months, so I got a new one.
The cot mattress is sprung (individual springs) so I didn't bother

messygarden · 21/01/2010 09:18

My DCs are 24m apart and I got a new mattress for the cot when the 2nd was born because that was the advice and I am a worrier.

EldonAve · 21/01/2010 09:47

DC1 & 2 used the same mattress
DC3 will get a new one as it is a bit grotty now due to puke etc

fernie3 · 21/01/2010 10:01

We got new a new matress, more because my both my older ones were sicky babies and I just wanted a fresh one for a newborn.

heth1980 · 21/01/2010 10:03

I've got a new mattress for DD2...to me it just wasn't worth the risk - I'm a worrier like messygarden and would rather have peace of mind!

jeee · 21/01/2010 10:12

I kept the same mattress for DCs 2 & 3, but got a new one for no.4. I think that if you have any doubts at all buy a new one for your own peace of mind.

thedollshouse · 21/01/2010 10:18

I will be buying a new mattress because it is a risk I don't want to take. I don't think they are that expensive and it the money spent will be worth it for peace of mind.

The scientific stuff is here:

www.sidsandkids.org/documents/SecondhandmattressesInformationStatement.pdf

In summary:

"Although there is some evidence to show that there is a higher incidence of SIDS on some second hand mattresses, it is not known what condition these mattresses were in or what position these babies slept in. There is no evidence to show that the risk of SIDS increases for babies who sleep
on their back and on a firm, clean, well fitting mattress that is in good condition."

Ninni · 21/01/2010 11:31

This is also from FSIDS website:

I?m expecting my second baby and I?m not sure if I should buy a new cot mattress. What do you think?

Jean Simons, our Helpline manager replies:
"Ideally you should buy a new mattress. If you are not able to do this, use the one you have, as long as it was made with a completely waterproof cover and has no tears, cracks or holes. Clean and dry it thoroughly. Check that the mattress is in good condition; is firm, not soft; fits the cot without any gaps; and doesn?t sag. It is very important that your baby?s mattress is kept clean and dry".

I think most of you're right, do you want to take the risk?

Just spoke to them actually and they said as long as the mattress was covered in PVC and was in good condition, no sagging or rips in the plastic, it was fine. Just give it a good clean.

I'm not getting a new mattress for my 2nd child.
The one currently in the cot and still used by DD has a completely waterproof cover with no tears, cracks or holes. She was only sick in it once and I was able to wipe it clean with antibac spray so I see no problem with using for number 2.
I would view things differently if it had a fabric finish and couldn't be properly cleaned.

MummyTumble · 21/01/2010 18:38

i buy a new one each time, the money is worth my peace of mind and sanity

New Baby New Mattress?

How it all started
In the late 80’s there was a theory that the "then" recently introduced fire retardant chemicals used in the production of foam, when mixed with the body fluids and warmth and moisture from a baby caused a toxic gas.This gas was said to affect the baby’s breathing and heart functions.

When this news hit the press it caused chaos in the baby mattress industry and utter confusion and immense worry for parents. The government responded by getting together a team of experts that worked tirelessly on this theory and found “no evidence of harm to infants from the use of fire retardant chemicals in cot mattresses!”

So who do you believe?
As a result of the government's Limerick Report and a also a belief that perhaps the toxic gas theory might have some credibility some components in foam mattress production were changed, but the fire retardant requirement in cot mattresses stood and is still law.

UK fire regulations makes us put fire retardant chemicals in baby mattresses, It is not an EU requirement, only U.K baby mattresses have to conform.

The advice from The Foundation for the Study Of Infant Deaths, now called The Lullaby Trust. recommended a whole host of measures “Back to Sleep”, no bumpers, good ventilation, avoid your baby overheating and also “New Baby New Mattress” and if you are buying a mattress ensure it has a waterproof wipe clean cover and it is firm, and gives good support.

. The “New Baby New Mattress” advice was because of the following dangers:-

  1. Using a second hand mattress that was not looked after and you don’t know the history the mattress could be soiled with baby fluids and a fungus allowed to grow.

  2. With wear and tear the foam could have lost its support, foam does not like heat weight and damp (which is exactly what a baby is.) this causes the foam to become weak and dip or dent.

  3. Good ventilation and baby's sleeping on their backs so they take in more air and if there is any toxic fumes from the mattress, they would not be inhaled by the baby

  4. Sleep your baby on a wipe clean waterproof cover that makes a seal between the foam and your baby

The response to this advice was amazing, cot deaths in the UK dropped dramatically.

One small conflict in this advice is :- If you put as baby on a waterproof cover you restrict the airflow to the baby. Also PVC is now considered carcinogenic. Don’t worry technology has moved on as you will see, we can improve on this

“New baby New Mattress”
Consider a baby mattress where the core is protected by a separate machine washable waterproof wipe clean cover made from PU not PVC. So no body fluids get to interact with the foam’s fire retardant chemicals.

On top of the waterproof protective cover you zip a highly breathable temperature controlling topper like Coolmax© and Maxispace and also have a spare topper so you can keep your mattress clean.

But we still have a support problem to solve:-
The core is made of springs or pocket springs encapsulated in foam. 95% of current quality foam mattresses are made of 24/130 foam (28 CMHR) it passes British standards. This foam cannot be more than 2 cm deep each side. The springs are 6 cm deep and you cannot have a baby mattress deeper than 10 cm according to British standards. So 2 cm foam on the base and 6 cm of springs and 2 cm of foam on top makes up the 10 cm.

On average a good quality mattress with 28 CMHR foam will last at most 18 months to 2 years before it dents under normal activity. The 2 cm layer of foam surrenders first. If you are using a cot bed you will most probably have to buy a second mattress.

Consider a mattress made from 30/150 foam or even 50/215 foam, It is still 2 cm deep but this foam will not dip or dent and last 5 - 7 years or more if turned as per instructions and costs only a few pounds more and gives far better support from day one.

Also the world is changing we are all getting more aware of the effects of waste on our planet. more thought going what we put in landfill. Foam takes 1 million years to biodegrade, Food for thought?

So consider buying a cot mattress that offers:-

  1. Protection of the core from body fluids,

  2. A way to keep your cot mattress clean and hygienic,

  3. Excellent support for many years so your cot mattress will not dip or dent.

When your first baby has finished using the cot mattress providing the mattress has no dents in it. It has been kept clean, no body fluids have got to the core it will probably look like a new mattress then no reason why you should not use it again.

There are 650.000 babies born in the UK. We could greatly reduce the landfill if we did not buy so many disposable cot mattresses. Yes save the landfill by more than 3000 tons a year or if laid end to end almost enough to go from Lands End to John 'O' Groats every year.

When you dispose of your old cot mattress and take it to the tip. Please rip out the inner metal springs unit, only takes 5 minutes and put them in the metal recycling bin.

Natural Mattresses
The same principles apply in terms of using your natural mattress for a second child. However you cannot have a natural waterproof protective cover that is highly breathable. but there are options.

  1. Certainly a top quality lambswool and coir mattress or lambswool coir and pocket springs will not dent or dip and should last for 5 - 7 years

  2. There is a school of thought that says as body fluids do not react to natural fibres as they do with the fire retardant chemicals in foam so then you do not need waterproof protection to the core. Many disagree! why take the risk, it is better to keep the core clean from bacterial growth. To do this you need a waterproof cover but it will not be 100% natural.

  3. You can get a 93 % natural cover with 7 % PU sandwiched in the middle of two layers of brushed cotton (OUTLUX)
