Are all baby/toddler 2.5 tog sleeping bags created equal?

I have, since my DS was a baby struggled with sleeping bags and keeping him warm in the colder months, overnight.

We have had various bags, from supermarket brands to John Lewis to more expensive merino wool wool ones.

The merino one claimed to be 3 tog but it didn’t keep him warm at all last winter and it was relegated to a spring/autumn bag. Now the weather has turned (up north!) very cool, we have had to move to his new winter 2.5 tog John Lewis bag but even at this time of year, that’s not keeping him warm and he’s waking various times in the night to tell he he’s cold, he also feels cold to touch. The room temp is about 21/22 degrees. He is wearing pyjamas, underneath with no vest (yet) which obviously i’m going to have to add in going forward.

Even if the vest fixes things for now, this solution won’t cut the mustard when the real cold weather hits.

I’d Like to avoid blankets, etc as he’s such a restless sleeper and rolls around the cot all night. He is 2.

So my question is, have you experienced the same? Have you found some brands better than others? How did you resolve?

Our little man was born in May into a heatwave followed by a hot summer so I feel like he’s got used to being warm and snug. We’re already struggling with him waking up cold in a 1 tog or 1.5 tog when the rooms 22 degrees(average). He sleeps with babygrow and short sleeved vest underneath.

I’ve seen sleep bags that have arms also so safer than blanket etc but possibly would help with keeping little ones snug?

ive heard good things about the long sleeve love to dream ones as they’ve been rated well independently.We loved there arms up swaddles earlier on and found the quality really good.

Has he always run cold? Being this cold in a 22 degree room is quite abnormal. Sleeping bags with arms exist which may help.

Try socks and a vest.

Does he feel cold when he wakes?

Slumber sac are the best. They have arms that can detach, but sounds like you would want to keep them on.

The sizing is very generous and they seem much more comfy and cosy than other ones we have had. They are expensive, but I think it’s justified

It’s not the cheapest but I’ve always used a 1.5 tog sleeping bag, and then kept a small oil filled radiator in their rooms at a low to medium level (depending on how cold it is) so that their rooms are always around 19-20 degrees.

I suppose yes and no to him always running cold. We have this issue and always have at night, but during the day (running about, etc) or daytime naps he can be sweaty. This summer his nickname was sweatyhead actually! Seems to be a nighttime issue only.

DH is a bit of a softy when it comes to being cold so perhaps this is where it comes from - he does suffer with raynauds actually.

He often feels cold when waking yes, particularly hands and face and when I feel inside his bag, he’s certainly not as warm as me.

The extremities aren't as reliable an indicator as the core, but if it's waking him then you want it sorted!

I'd go with socks in the bag, long PJs and a sleeved suit. You used to be able to get 3-4 tog ones.

Thanks. I’ll take a look as we are definitely in need of a solution when winter hits!

Thanks, I’ll give that a try.

Yes, I suspected it might be a thing of the time and safe sleeping etc, a bit like the NHS telling you to give your baby practically a cold bath 😳 he certainly wasn’t having any of that 😆

I'd put a vest (long sleeved in winter) underneath the pyjamas. You can even add a cardigan if he's really cold. And socks. Im sure ive seen vests with padded sleeves somewhere too (might have been grobag branded)

We used a 3.5 tog sleeping bag with arms from Jojo Maman to keep our two year old warm last winter. It’s roomy enough so you could layer pyjamas and a vest with long sleeves underneath if you need to. I do wonder if the concern about young babies over heating and the risk of SIDS from that leads manufacturers to not make sleeping bags for older babies and toddlers warm enough.

I know you said you were against blankets, but I would get him a duvet. Use a full single size one and the excess can then be tucked tightly under the mattress meaning he can’t get out as easily. Then layer up with thermal underwear, pjs and proper bed socks. In your position I would be loathed to spend more money on sleeping bags he’ll only use for a year (as presumably he’ll be moving to a bed with duvet in the next 12 months anyway?), and if he’s still cold with the ones you have, I don’t think you’ll find a huge difference with a new one anyway. Is there a draft in his room? A base temperature of 21/22 seems fine, so I wondered if he’s feeling cold air from a door/window?

I used Jojo maman 3.5 tog sleeping bags, I thought these were best. Had detachable arms and the arms and body were roomy enough to get layers underneath.
When it was really cold, I would use a vest and long sleeved babygrow.

I like the lovetodream footed sleeping bags. I think because they fit quite closely they keep the heat in. You can also put warm (adult) socks over the feet if needed. They do go up to 3.5 tog but we do fine with 2.5
