Dave and I thoroughly enjoy our front row seat to Esme's language development. Here's a little taste. (We especially love her male possessive pronoun "hims," which can also mean "he is.")
Last night I came across this post from Esme's baby days and showed it to her.
Mommy: Esme, who's this?
Esme: (After another look) I can't member hims name.
Mommy: That's Esme.
Esme: Yeah, dats Esme I was borned!
Mommy: Yes, that's you after you were born, when you were just a little baby.
(And I might have added, "A very bald baby!")
