Breast milk and diarrhea??

Thaydene • Wife and first time mother to my little monster. Baby boy born on 12/7/15: the day my life began 💙 thank you God 🙏🙏
First time mom! Bare with me...my baby is 5 days old....my milk just started coming in yesterday...he's therefore getting less formula...as of today it's been all Breast milk (expressed and directly to Breast). I've noticed that his stool is loose and more "explosive." He's in no pain or discomfort. Sleeps well eats well. Peeing well. He just farts explodes and goes back to business as usual. Has anyone experienced this??? Is it "normal?" I read that as long as he's comfortable and in no discomfort its "okay" (maybe he's still going through the 'poop changes' that happens at he beginning of life). ANY input will be helpful 😊😊
