My child smells like poop even though she isnt poopy. she has umbilical hernia and heart murmurs?

Hygiene, see doctor: Make sure you are cleaning her well- into the folds of her genital area and other folds of her body (germs can get trapped in those areas and create odors). If she is bathing regularly, but you still feel she has an unpleasant odor, check with her doctor. She may have an infection of urine or stool.

See Your Doctor Now: More info is needed about your child: is she still in diapers, potty-trained, bowel patterns, detailed medical history & more. Constipation is common in picky eaters at this age; can cause bloating/flatulence. Congenital anatomic defects can lead to serious constipation w/ odor, urinary tract infections can produce odor. See your child's doctor now for a thorough history & physical examination.
