My sister's 3 yo is scheduled to have a colonoscopy next Wednesday - she's been having constipation issues since she was apprx. 8 months. They drew blood already and didn't find anything in the tests they did on the blood. She does eat fruits and veggies - not as much water as she should be getting but not so little that it she should be as constipated as she is. Just wanted to see if any of you ladies have been through anything like this or heard of anything non-surgical that helped. TIA!
