Another one here with sweaty little boys!

Mine are especially bad when they're asleep. Often DS1 will wake up from a sleep completely drenched from the chin up - especially in his hair as well. He's been a big sweater since he was a baby (almost 3 now). He also has a very decent head of hair, but DS2 is only 9 months, and he doesn't have a huge amount of hair yet and even he sweats profusely while he's asleep. It doesn't matter how much or how little they are wearing, they still sweat heaps.

I always check their temps too and they're fine, so I've put it down to genes (they have a grandparent from each side who are big sweaters ) and figure they're just my hot-blooded little boys
