Nuts have great nutritional value, but we opted to forgo nuts until age three. At 18 months, in their raw form, they could be a considered a choking hazard. But, more significantly, they do pose a serious allergy threat. Here's what our pediatrician told us, in a nutshell (sorry, I couldn't help myself): children who are predisposed to have a nut allergy can actually eliminate the allergy entirely by abstaining from nuts for the first three years of life. In other words, if Baby M is predestined to have a nut allergy, by simply NOT eating nuts before she's three years old, Baby M will never even get the allergy. If Baby M does eat nuts before three, that can serve a trigger for the allergy and then she's stuck with it.
We have absolutely no history of nut allergies in our family, but it seemed a fairly easy thing to avoid for a great payoff.
Also, I'm not in the medical field at all, so I'm just regurgitating what I was told...
