Lol that's exactly what's happening is he's shedding. I was kinda freaking out like why is there so much of it everywhere! But like I said my pedi said it was completely normal. When I asked if I should put lotion on it she said just to let it shed and it will be gone soon.
My son had the same thing his first few weeks my pedi said its normal and it will just fall off. Just let it do its thing. Unfortunately it gets worse when you give them a bath but it will be gone in a couple weeks.
