My son is 5 weeks , he has pretty bad acne all over his face and now on his chest, I noticed on his forehead some spots look a little yellowish . Anything I can do to help with it ??

Also he is fussy, fussy when he is trying to poop, fussy when I have to burp him. How often should he be pooping ?? And it’s so hard to burp him . I feel so bad cause he looks like he’s struggling so hard to poop and Nothing . He also spits up just about every feeding, sometimes when He finally burps and sometimes an hour after feeding .

I talked to his dr about both, she said acne will go away on its on .. and we won’t worry bout switching formula till we noticed he isn’t gaining weight or he is losing it.
