When Ryan was 21 months old, (the exact age Lucas is now) I blogged here about his vocabulary of 4 words. 4 words! When I try to make a list of Lucas' words there are too many to write down.
Lucas' newest words he has learned from Ryan include "peepee" and "poopoo". Other cute words he says are "Ry-Ry" for Ryan and "pleeeeease" when he wants a snack.
