I would love to sic the linguists on my kids. Not sure how many specimens they've studied who have heard exclusively Mandarin/Taiwanese in their earliest months, been relocated to an all-English speaking household, and attend school 50 hours a week in the ghetto. Because Jada is older and her speech is more evolved than Aaron's, her voice is particularly interesting to listen to, especially when she says things like "Them chickens jackin' my style" or reads to herself at night in the sing-song cadence of her speech therapist ("And what is that? A spider. Good!").
Of the many rewards of parenthood, one I'm enjoying is helping our kids find their voice. What a unique one theirs will be.
