I really could devote a whole blog to the differences between how things are with the first baby versus the third, but here's just one little example: peanut butter. For those non-parents among you, for a very small number of children peanut butter is such a dangerous allergen that it can kill them pretty much on the spot. So you are supposed to wait a year or two, or even three or more, depending on your doctor's recommendation and your own personal inclinations. Or, as it turns out, the birth order of the baby in question. It goes like this:
Baby #1 (age 2): you offer a teeeeeny weeeeeny amount on each of several successive days until it is clear that the child is not going to have an allergic reaction.
Baby #2 (age approx. 18 months): Oh, thank goodness you're old enough to have peanut butter. Finally! Here ya go, babe, eat up!
Baby #3 (age 12 months): "Hey Mommy, I gave the baby my peanut butter! She really likes it!"
