Constipation?

Tori

My EBF 5 month old son has never gone any longer than 1 day without having a poopy diaper (and that only happened once). However, it has now been 3 days since he’s pooped. He’s been passing gas like normal and acting normal, too. Any suggestions as to what could be going on? What to do? I’m going to give his pediatrician’s office a call tomorrow morning if he still hasn’t pooped.
