My baby girl was like this, but she's been having weetabix, mashed bananas, avocado, and blueberries the last few days, and due to all that fiber, she's been going multiple times a day.
My LO gets very constipated and I would say if it carries on go to the GP and see if they can give you something to help! Xx
Try weetabix, this really helped my baby come off laxatives. She was on laxatives due to screaming when pooing but the fiber from weetabix has really helped and she hasn't had laxative in almost 2 months and no issues with pooing
