How heavy was your baby when he/she first slept for 8hours straight?

[Handsoff7]

My DD is 4.5months old but was 2 months early and small for dates so still only weighs around 10lbs.

She sleeps well but her limit is about 6hours at night. I suspect this is size related. Books and other posts generally talk about ages which is hard to interpret in my case.

How heavy were yours when they could go for a whole night?

Thanks for the help

Mine have been fine going down awake/self-settling, one from about 2 months old and one from 7 months.

Yes, they are so variable!

Unfortunately it hadn't translated into never bothering me at night...

Well, DD3 slept very well after the first month until she was 5 months old, possibly recovering from her birth. So by that measure, about 4 kg.

However, after 5 months, she began to wake up more and more in the night. I'd say she's now only started relatively reliably started sleeping 8 hours since she's been 4.5 yo or about 14kg.

I guess this might not be what you want to hear though...

weight didn't make a difference for me either. My first slept 7 hours in week one and soon went up to 8 or more hours. My last didn't sleep more than 3 hours until she was 18 months.

Completely agree about weight not being related.

Ds is on the 98th centile and has been around there since about 2 months old, but only slept through for the first time at 12 months, and even now at 14 months he still wakes up at least once most nights.

Dd however was smaller, between 50th and 90th centile and was sleeping through consistently from 7 months.

"The full 12 hours takes a bit longer" hahaha ds has slept 12 hours maybe 3 times in his life. I hate this assumption that dcs can, will or indeed need to sleep for 12 hours at a stretch - that is an amazingly longtime.

Absolutely agree Still - none of mine slept 12 hrs on a regular basis until they discovered 'lying in' as teens

Dt2 was 9lbs and slept for 8 hours every night after doing it the first time.

Dt1 was same but more sporadic e.g waking up for teething pain etc till about one year

DD1 slept in 4 hours bursts for nearly 3 years.

DD2 slept pretty much through from last feed to 7-8 am from about 2 weeks.

I did mostly the same with them both. Different babies.

when he hit thirteen. Years.

DD was 2 before she slept for longer than 4 hours at a time. DS has slept for 8 hours a night since 5 weeks... No rhyme or reason, just personality I think...

We're still waiting for DD to sleep more than about five hours at a time. She's 28 months....

About 8 months; she'd worked out how to roll on her tummy so would do that then sleep through.

In the months preceding that she'd only been waking once though, between 4-5am, then going down after she'd been fed, although I would dream feed her when I went to bed.

Mine only started sleeping through once he turned 4. Took him a looooong time!

A baby whose nutritional needs are met between 7am and 7pm (with a late feed at 10.30/11pm) will soon learn to sleep through the night (barring illness, etc). A baby who has been permitted to develop unhelpful sleep associations will be far more likely to wake multiple times and need a breast/dummy/rocking to settle.

Many do, some don't learn to sleep through the night "soon" though!

I seem to remember research that around 75% of babies sleep an 8 hour stretch by 12 months though.

DS1 10 weeks

DS2 bit of a blur really but think it was 3 months ish

All 3 of mine were between two and three.

Two words: Gina Ford.

Many thanks for your pearls of wisdom, Greedy.

Oh and none of mine has ever, ever slept 12 hours in 24, not even as newborns. Oldest is now 21 and sleeps 6/7 hours on a long night. 5-6 more common. As a newborn (3 or so wo) he was awake all day and largely somnolent all night but with quite a few wakenings. Not every child will sleep 12 hours. It's not some magical figure.

I ebf both of mine, dd slept for eight hours from about 12 weeks (she was probably about 12lbs). My ds, who is five and a half, has never slept all night (have the bags to prove it). He is the older child, we treated them exactly the same and he was a similar weight as dd at12 weeks, although is very slight now.
It obviously varies between children and I have come to the conclusion that it's intrinsic! Ds plays tennis, rugby, football, loves being out on his bike, scooters to school and has swimming lessons so it's not as if I don't tire him out lol

dd1 - Think she was about 9 - 12 weeks. She was quite a chilled baby, the sort who lie happily under a play gym. I put her down awake.

dd2 - She was about 2 year and 6 months. She was a very highly strung baby (still is quite highly strung) the sort who would scream blue murder if i laid her under a play gym. Attempts to put her down awake resulted in her screaming like she was being tortured (as Penguins put it )

My boys were identical weights at birth, give or take 20g (both 3.8 kg / about 8lb 6) both ebf, both put on weight at similar rates, both treated the same - DS1 slept through regularly from 7 months (not 12 hrs, but 10 - none of my kids sleep 12 hrs) and DS1 did so for the first time at 2.7, and has still only managed it a handful of times at 3.3 - as he is 16kg and 1 meter 4cm I doubt it is weight related :o

DD was 9lb 2oz at birth and didn't sleep through til she was 2.
