Hello, I have a three week old baby and have been exclusively only bottle feeding. Started her on Similac pro sensitive and I’m starting to notice that maybe this isn’t the right formula for her. She’s usually fine after a feeding but will have trouble falling asleep and then becomes fussy. She’s starting to spit up a lot more now too and becomes extremely gassy, sometimes looks like it’s painful.. I’m a FTM so I’m still learning but I am seeing this become more of an issue. Anyone ever experience this with their LO with this formula?
