Why does my 2 year old farts smell so bad. she is a very picky eater and eats the same thing almost everyday but no vegetables. is something wrong?

You'd have to see : her pediatrician for a check-up to know for sure, but if she has no other GI symptoms, she's probably okay. At family sit-down meals, offer fruits, vegetables, whole grains & beans. Model eating them; don't nudge. Limit milk to 16 oz./day in open-mouth cups only with meals. Offer water only for thirst, in open-mouth cups. Read " How To Get Your Kid To Eat But Not Too Much" by Ellyn Satter.
