I had never heard of restricting nuts anywhere. Not from any pregnancy book, any of my OB's etc, until my sister who was pregnant was told by her Dr not to eat peanuts. I was like ya right!! It's probably due to the fact that there is a TEENY TINY chance of baby developing an allergy after birth?? But wow, so many restrictions. I dont eat peanuts often, but I do have the occasional PB&J or snickers bar. And I will continue to eat them. I think if you are worried about allergies, then once your child is born you should wait the recommended 3 years(if your family has an allergy history) before giving them any peanuts.
