This might be a bit precious first born but...
My 5 month old seems to get sweaty fairly often. A few times it has happened in his car seat - I mean like soaked, there was a round wet patch where his head had been. I know I am not over dressing him as he rarely wears more than a vest and a sleep suit since it has been above freezing outside - but often less (either no vest or just a vest & joggers or a all-in-one w/no feet, etc). I have a groegg thing in the house & lately it has been reliably between 19 & 21 degrees.
He also tends to get really sweaty when I am nursing him. His whole head feels warm but where his head is resting on my arm always gets so sweaty! I tend to be a bit clammy myself but I just want to check it is normal and not an indication that something might be wrong.
Over the weekend I was carrying him in a sling (oscha 100% cotton) & he was wearing a short sleeve/shorts all in one suit and he was so sweaty. It wasn't even hot!
The past few times we've been on longer car journeys I try to make sure that air is flowing in the back seat but it is tricky as most cars don't even have vents! I've also dressed him even lighter (just a vest or a t-shirt) and finished dressing when arrived.
If this is normal - any advice on how I can keep him comfortable. Is he just a hot baby?(
