My baby seems to have bad constipation every night. It was really bad last night, we were up till 4 am with her. Tonight it seems to be happening again, why does it happen every night. I was very careful about what I ate today and she didn't even nurse as much as normal, I think she was exhausted from last night. She slept alot today. What can I do for her, the usual doesn't work, bouncing, laying on tummy, patting back, rubbing tummy, baths, etc. Someone suggested an enema to me but I don't know if this is a good idea or not. What should I do?
