My baby boy has moved on from the constipation stage. He is 8 months old and I noticed starting from about 10 days ago his pooh is very runny. He poohs 2 to 3 times a day in smaller amounts. He used to poop one big one a day but now it's smaller portions and runny texture. Does anyone have any idea why? He drinks 3-4 bottles a day with 2 solid feedings a day.
