My DS is 7days old and sometimes we've noticed he gets a slightly damp back when he's been in the Moses basket. Could he be too hot and sweating? Or is this dribble making it's way down (it doesn't stain a white babygro so can't be pee, poo or vomit) I seem to remember being told babies can't regulate their temperature which I took to mean couldn't sweat. He is alert and happy and we have room thermometer & a monitor which would tell if things were too hot for him but you know what it's like I can't help but worry!
