My baby is gassy. Is this caused by something in my diet?

Does a mom need to watch everything she eats to avoid having a gassy baby?

The idea that certain foods in any mom’s diet will cause gas in her baby is incredibly persistent but is not founded in research. If certain foods in moms’ diets were an overall problem for most babies, we would expect that cultures that emphasize those foods would have more gassy and fussy babies, but this does not occur at all.
