1 year old baby poo 4-5 times a day.

My baby usually poo 3 times a day. Since he turned 1 year old and changed formula to stage 2, he poo almost every after feed-milk/solids. So 4-5 poo a day. Doesn’t look like Diarrhea. Normal poo, No fever, vomiting. Anyone has this experience? Is it because of new formula introduced?
