4.5 year old was constipated dr gave her anema and she passed stool. after whole night again she z complaining of stomach ache. aftr eatin she vomits.

Take her back to her: doctor. If she still has stool in her colon, finish the clean-out. Then give daily Miralax (polyethylene glycol) at a dose that yields soft stools for at least 6 months & have her sit on the toilet for 15 minutes, 15 minutes after dinner nightly with her feet on a stool, like a Little Looster, blowing bubbles to help push.
