5 wk old pooping problems

Jessica

Considering changing formulas and wanted some perspective! My 5 week old hasn’t had a BM in >24 hours. I did read that this can be ‘normal’ for formula fed babies but he just seems so uncomfortable and fussy. We are feeding Similac Pro-Advance (started on it while in the hospital so I never really got to research other kinds). A friend told me her LO had tummy troubles on this formula as well, wondering if it’s a common issue?
