Summary: Researchers followed over 300 mother/child pairs to determine the effect on babies of eating different amounts of fish during pregnancy. Moms who eat more than two servings of fish per week during their second trimester of pregnancy, particularly lower-mercury fish, have three-year-olds with the most advanced motor skills. Comparatively, moms who limit their seafood to two servings (12 ounces) of seafood per week or less see no cognitive benefit for their children.
