40 weeks...

So, today Nate is 40 weeks old! Yea! He is now out of the womb as long as he was in it.

The gestation for a baby is 40 weeks, and Nate was 2 weeks late, so his gestational age was 42 weeks. Yet, I wasn't pregnant for the first 2 weeks, because gestational age is calculated by last menstrual period. The fetal age is about 2 weeks shorter, since a woman ovulates around 2 weeks following her period. Therefore, the fetal age of a baby full term is 38 weeks, but Nate was 2 weeks late, so his fetal age was 40 weeks at birth. Won't Nate love to read this when he reads this blog when he gets older ;-)
