Again I’ve said this a million times it seems like but i haven’t had a newborn in 7 years and I need some answers. I had little man on gentle ease enfamil and I just switched him to the yellow can of enfamil just yesterday cause he’s been VERY gassy on gentlease so I thought I’d try the yellow can. Well every time he poops it burns his poor butt and make it’s really red and bleeds on his skin. Also he pooped while he was napping and I didn’t know it so I have a feeling that’s why he developed a rash. I hate hearing him scream when I wipe him. Will he be ok? Do you think it’s because I didn’t get to his poo diaper fast enough while he was napping or is it due to me changing his formula?
