My daughter is 10 weeks we are strictly on formula at this point. Today was her first "hard poop" ( like peanut butter) all were liquid until now. She was really straining and cried in pain. I just want to know if this normal and will the pain eventually go away for her? Also is there anything I can do to help her? Thank you in advance!
