7 m. old excessive sweating while napping--what is this?

[kismetbaby]

We are traveling and my 7 m. old is experiencing his first 80+ temps. Ever since we have been in the heat he has been sweating every time he sleeps. When he wakes his head and the sheet beneath his head is very wet. I haven't had a blanket on him while he sleeps, just the clothes he is wearing. Is this due to the heat or something else? He doesn't have a fever.

I wouldn't be worried except that it is causing some dehydration. His pees have become dark and much less frequent and he is also constipated. I am nursing him as much as possible. Is there anything else I can do? When should I be worried about dehydration?

what is he wearing? in that heat babe is only in a diaper, sometimes a short-sleeved onesie. as for dehydration, are you giving him water? at that age both my kids got sippy cups of water in the car and they were also nearby while playing. between that and nursing, we never had a problem.

This would happen with my LO as well. She is the biggest sweaty head! A couple months ago she too began having really dark urine and constipation, I ended up offering a little water in between sessions. She loves it and it really helped out the dehydration issues. I was really afraid to offer water because I had heard not to give a BF'ing baby any because it could fill them up too much, but I figured it had to be better than constipation! Also, I bought a cup with a straw so she could drink it by herself, most ends up on her then in her, but she has a great time and gets enough to help her out a little, but not fill her up. I have noticed no decrease in feedings at all.
Good luck to you!

DS sweats in his sleep. One reliable way to tell when he falls asleep is I can suddenly smell him beginning to sweat (not a gross gym socks smell, just nice clean baby sweat smell), and he gets sweat beading up on the bridge of his nose.
