Baby Cha Milk

Little Guy's vocabulary seems to be doubling in size every day.  He is mimicking anything you say (scary!!) and really into narrating whatever it is we're doing at the moment (this is precious now, I may be able to see how it could start to wear on the nerves).  He is also becoming more and more infatuated with his little brother and everything he does.  He constantly checks in on the baby and always wants to know where he is if he can't see him.  Well today I finished up nursing Mr. Wyatt and was also giving Little Guy a bath (Daddy's out of town), when Little Guy announced "Baby all done cha milk".  I've tried explaining that Little Guy gets different milk than Mr. Wyatt and Mr. Wyatt drinks milk from Mommy just for babies...and apparently I make "cha milk" just for babies too.
