I hesitated in posting this, but it's a study by a reputable researcher.
Peanuts During Pregnancy May Lead to Later Allergy
Heavy emphasis on the MAY.
I know folks who avoided completely with their second pregnancies and still had a PA child.
The research goes back and forth and frankly I'm not sure what to believe. All I know is that I can't beat myself up over something I may or may not have done 'right' during my pregnancy.
And you shouldn't either.
