Vocabulary of B

Is it just me or do girls gain their vocabulary at a faster rate/earlier age? I swear my son didn't say more than a few words until he was maybe 2 or older. (Of course he pretty much went from one word utterings to almost full sentences about overnight!).

Baby B is almost 14 months, and her verbal skills are just amazing to me. When she sees daddy she will say "Hi Daayee!" when she vacates my lap she will wave and say "buh-bye seeya."

She will point and say "wassat?"

This morning she was calling to our little dog sally "saay saay." She can say the other dog's name pretty good too - "jo-jo." My son D named her when he was a little over 2 years old. Around the time my husband brought her home, D was saying "Jo-Jo" quite a bit. Around here, they call the potato wedges (like from KFC) Jo-Jo's and he really liked them.

And she loves her big brother "Duh Duh"

It's been quite interesting having a boy and a girl within a couple years of each other, in comparing how and when they reach certain milestones. I do know that all children are different and regardless, reach those milestones in their own time. But through my observation, there does seem to be a difference between the genders. It seems to me that boys reach those physical feats sooner than the girls. D was crawling, pulling himself up, cruising and walking much earlier than B. And I remember my neice, who is 2 mos younger than D, also seemed to reach those physical types of milestones a little later than he did (while her verbal skills continued to be way ahead of his). But on the other hand, it seems that the motor skills, hand-eye coordination and manipulation of fingers and objects happens a little quicker with the girls. And the girls also reach those social milestones a little quicker.

Has anyone else noticed these kinds of gender differences in reaching milestones?
