I need help! I don't see my daughter's doctor for a week and a half and I'm concerned with something. Usually she poops twice a day, but for the past 2 weeks it's been once a day. She's strictly formula fed. She grunts so hard and her face gets red when she tries to poop, it's like she's struggling to get it out. Today her poop was.. weird. It was like a ball. I'll post a picture in the comments.
