Hoping to prevent this allergy in children, some women don't eat peanuts during pregnancy and breastfeeding.
Lauren's mom says she never went near them.
But is avoiding peanuts and other allergenic foods like fish, milk and eggs necessary?
In 2000, the American Academy of Pediatrics issued a report suggesting women with a family history of allergies may want to avoid those foods while pregnant and breastfeeding.
Laurens' allergist Dr. Scott Sicherer didn't think that was realistic.
He says there isn't much research that shows avoiding these foods makes a difference.
Now the academy has published a new report in its journal, "Pediatrics" which Dr. Sicherer has helped to write.
The reports also states there is no convincing evidence that feeding hypo-allergenic formula to babies or even delaying introducing certain foods to the diet like fish and eggs can prevent allergies.
Dr. Sicherer says more study is needed on how allergies develop.
However, it is still suggested that moms breastfeed to help protects against some allergies.
