baby rash.

okay i need some help getting rid of my baby’s rash. i’ve used huggies, luvs, and now back to parents choice diapers. i’m not sure if her rash was caused by the huggies or if it was caused from her pooping so much. it’s all over her area and a little on her butt cheeks. i feel so bad because she’s been like this since wednesday. i’ve tried just about everything. petroleum jelly or whatever it is, a&d, and budroexs butt paste (idk how to spell it). it would clear up a little then she would poop and it would go right back to the way it was. i change her diaper every 2 hours unless it’s poopy or if i can feel that her diaper is full then i change it right away. it doesn’t seem to bother her unless it’s first thing in the morning or when we get back from walking. please no negative comments. i’m a young ftm and i’m trying to help my baby out. she has a dr appt first thing in the morning.
