Sweaty Baby

I have a 3 month old baby boy who lives in onesies because he gets hot super easy. He's been sleeping in a co-sleeper in our bedroom and I am ready for him to graduate to his crib. Problem is, he sweats way too much in the crib. We have a mattress pad on top of the mattress and a thin sheet. I have stuck him in there for naps but he wakes up sooner. I pick him up from out of the crib and his hair and back are wet with sweat. Anyone have any ideas as to how to keep him from sweating so much? I've thought about a cooling mattress pad, but I don't even know if these things exist. He currently loves to be swaddled, so we swaddle him with a onsie on. He's fine in the co-sleeper...he doesn't wake up sweating, it's just in his crib.

What can I do next?

He will probably grow out of this. The swaddling is probably a large part of the problem. Babies don't usually stay swaddled much past 3 months anyway though. Once they can roll/move around a bit, the swaddling will come off by itself.

But I wanted to suggest "sheet savers". It's a waterproof sheet that tucks over the crib sheet. It is much easier to change than a fitted sheet. It would be useful for this sweaty phase, but I also find it very useful for diaper leaks and spitting up/vomiting. It's a real pain to change a fitted sheet in the middle of the night when you are half asleep.

Plastic, ployester, nylon. Remove them from the crib. Get all COTTON (natural and breathes)
If cost is an issue, check thrift stores.
I would only dress him in cotton.(linen, hemp and silk are also natural). same for baby blankets etc. and he will not want swaddled much longer!
Some of us actually cannot abide wearing those plastic based fabrics (or sleeping on them). Some of us actually get RASHES from them.
I believe polyesters are PETROLEUM based, gross huh? Talk about fossil fuel dependency. :D

There is probably WAY more plastic in his crib than in his co-sleeper.

He probably has a plastic-covered matress, a plastic sheet liner, a plastic-coated matress pad and a plastic-covered disposable diaper. Each of these four things by themselves will contribute to sweating. Add them all together and you get one soggy baby. My daughter gets sweaty at night very easily too.

My suggestion: Get rid of the plastic-lined matress cover and the plastic crib-sheet. Put a thick 100% cotton towel down on the matress instead. Make sure his sheets are 100% cotton. (Many baby sheets have a polyester blend.) In the end, though, you may just have a baby who sleeps warm.

Good Luck!

My three month old is the same way. We turn the fan on in her room when she is sleeping on low. It seems to help.

Have you tried not using the mattress pad in the crib? We took the mattess pad off completely because our daughter would sweat a lot with it on. Hope this helps.

You may also want to turn a ceiling fan or portable fan on low in his room to keep air circulating and cooling him without him getting too cool.

I would make sure everything is ALL cotton - cotton breathes much better than polyester and allows the skin to cool- just an idea, good luck!

I've noticed that people tend to put a crib with one side against a wall. If this is the case with your son's crib, you might try turning it so that either an end is against the wall, or even move it to the center of the room so that air circulates better around him.
Someone suggested getting rid of the plastic covered mattress.
I think it might be difficult to find one that isn't plastic covered, and if you put a thick cotton pad (a heavy bath towel would likely do the trick) under a cotton sheet, it should alleviate most of the problem from the plastic mattress cover.

Hi E.,

The fact that he only has this problem in the crib makes me wonder if he might have an allergy to something in the mattress. I don't want to worry you but I would not put him to sleep in there until you figure this out. If he was a hot sleeper in your bed that might be different but I would really be concerned about an allergy. I wonder if the mattress contains latex? Crib mattresses usually have a surface that is waterproof, maybe that contains latex? The mattress should have a label which shows what it is made of or you can look up the brand on the internet.

Congratulations on your little one! We have a 22 month old boy and well, he gets hot just like his parents.

I've always been told that a baby will let you know if they are uncomfortable due to external and internal temperatures. With that said, I do keep close eyes on his flushed cheeks during activity and offer him water frequently. I also recognize the change in weather temps and well, I'm sure you do this too...adjust clothing and blankets accordingly. I do not use the footie pajamas due to our son getting too warm; however, I do put socks on him especially during the cooler months. His blanket flops off him thru out the night, but I have yet to check on him and note that he is too cold or too hot. He continues to sleep just fine.

I realize our boys are distant in age; however, some children just seem to sweat more than others. And I would imagine your 3 month old is still regulating his normal body temp outside of your womb.

Our son also gets the wet head when he sleeps in his crib, but I think sometimes it's a combination of teething drool and yes, bed sweats (I still get bed sweats at 36!). I do use a small fan if it's too warm just to help the air circulate. We also use a humidifier especially when the heater is on. I don't know about the cooling pad, this seems a bit much to me and well, could pose some additional problems (too cold at the temples and ears). I suggest trial and error and give him time to adjust to his crib and new room. Observe and adjust, that's my motto!

If you are truly concerned, discuss further with your pediatrician. They may be able to provide some additional insight. Good luck!

Try removing the mattress pad and putting a fan on low. Also, swaddling is very hot. He may also work up a sweat trying to get out of the swaddling (even unwittingly in his sleep). He's probably outgrown needing the swaddling. Try just a lightweight cotton sleep sack either with our without a onsie. We got our sons at Babies R Us and love it.
