So I have a question for moms with a 2 month old or moms with experience in switching formulas
my son is 2 months old had has has spit up issues since he was 2 weeks old. he spits up all the time all day long. I switched him from similac advanced to similac sensitive and it helps but not much, he stopped vomiting but still spit up 2 to 3 times after every feeding. sometimes alot sometimes alittle, sometimes curdled looking, sometimes milking looking. he has been on the similac sensitive for a month and an half now. I decided to switch him again to similac spit up. I switched him gradually like I'm supposed to. well today was his first day completely on the spit up formula and has had server painful gas all day and cries during feedings which he has never done. my question is do I leave him on the new formula for at least a week or should I switch him back tomarrow? I just don't know what to do and I hate to see him in pain like this.
