My 7 year old daughter has had problems with constiopation every since she was born (she's now on Miralax). Occasionally she will wet the bed in the middle of the night and she will also occasionally wake up vomiting for no obvious reason. I think I've read somehwere that vomiting and bed wetting can sometimes be triggered from constipation. Does anyone else's children have these symptoms? Any other ideas on how to control it? THANX!
