Yuh baby acne definetly bothers parents more than the babes.
My daughter had it bad...All over her face and her scalp. And I worried about it.
I left it alone and it cleared up by the time she was 7 weeks old.
Soaps just dry it out even more. So i tried to avoid harsh body washes etc.
My dd only gained 7 OUNCES in 2 months.
I was concerned and the dr. said my milk supply diminished due to Micronor Birth Control Pill.
She also didn't gain any length.
She is alert and happy and playful.
But I had to stop breastfeeding.
The nurse said its normal for babies to plateau during certain months and have growth spurts during others.
Sooo if you are worried, I'd talk to your ped/dr.
