My baby is a week old and I changed her formula from enfamil to Similac. I already regret it. She has been crawling up my chest and turning red. I knew she was straining to go. She finally had her bowel movement and she had only missed a day but still I don’t want her to be in pain. Any suggestions ladies? She’s just a week old so I know I can’t do a whole lot but I think she’s going back to enfamil tomorrow 😑😞😞☹️
