It seems no one knows, two completely contradictory evidences have been concluded so far.

"The number of people in the UK who may be allergic to nuts is increasing. Research from 2002 shows that one in 70 children is allergic to peanuts, compared to one in 200 ten years before. More recently, a report was published suggesting a quarter of a million children (one in 50) in the UK are allergic to nuts."

"The exact reasons why some people are allergic to nuts aren't fully understood at present. There is some evidence that children who are given nuts early on in their diet may become sensitised. This may also happen before the baby is born while he/she is still in the womb. It's possible that a child may develop a nut allergy after birth if his/her mother eats nuts while she is breastfeeding. However, new evidence suggests that this may not be the case and it may be necessary to expose babies to possible food allergens so they don't become sensitised to them."
