I only bathed him often if he got too hot after being out and about all day to cool him off. I try not to take him out since it's been so hot lately and cool the car down first if I have to.
I read not to put lotion on it because it can block the pores making it worse and bathing them too often will only dry out their skin. I wiped him down daily with just a baby wipe to keep his skin clean. Just make sure not to put any clothing or blankets on her making her too hot. My son runs really hot so I just keep him in a onesie and only cover him up at night. I was worried he'd be cold so I'd swaddle him but it was making it worse. Not a whole lot you can do but keep baby cool and it will go away in a couple days. :) @mommyof2beautys
