Yes, it is safe. There are foods that women should definitely avoid, such as high-mercury fish, raw fish, and deli meats. The Food and Drug Administration (FDA) has made these recommendations. But neither the FDA nor the medical literature indicates that peanut butter is unsafe to eat during pregnancy. There isnt any proven risk of passing along an allergy to the baby.

Most women who eat peanuts or peanut butter during pregnancy will have children without allergies, but this exposure does seem to increase the risk.There is a suggestion in the medical literature that women who eat peanuts one or more times a week during pregnancy or who have more exposure to peanuts during their third trimester of pregnancy may be more likely to have children with peanut allergies. A family history of allergies increases this risk.
I recommend limiting peanut intake in the third trimester and while breastfeeding, especially if you have a family history of allergies. This wont necessarily protect your child from developing an allergy, but its a good precautionary measure.

Peanut butter is great source of protein. If you dont personally have a peanut allergy, I dont think you should be concerned that your child will develop an allergy if you eat peanut butter while youre pregnant. And even if you or one of your immediate family members has a peanut allergy, it doesnt mean that your child will definitely be allergic.
Children only inherit a tendency to be allergic. There's no real evidence that being exposed to peanuts or peanut butter in the womb will increase a childs risk of having a peanut allergy. However, if you do have a strong family history of peanut allergy, you may want to be more cautious about when you first introduce peanut butter to your child. (Of course, if the family history is that strong, you probably wont be serving peanut butter in your home.) Always talk to your childs doctor before introducing new foods during the early years.
