Congratulations on your pregnancy! The answer to your question is not a straightforward "yes" or "no". As you may have observed, parents with allergies are much more likely to have kids with allergies. Twins have a 70% chance of having similar allergies. However, it appears that what is actually genetically handed down is the tendency to develop allergies and the severity of allergies - not necessarily the specific allergy. For example, a parent who is allergic to peanuts, might have a child who is allergic to pollen. In your case, your child is more likely to develop allergies than the child of a parent without allergies, but we do not know for sure if they will have allergies or not, and if they do develop allergies, we do not know if they will be allergic to peanuts or if it will be something else they are allergic to. Stay healthy, Dr. Jeff M.D.
