It's so amazing to witness Jake's development, both physical and mental. Recently he made huge strides forward linguistically, and is finally using verbs. Sometimes he even speaks in complete sentences, and it's almost as though you can have a conversation with him!
It's still difficult to understand everything he says (articulation isn't so good yet), but obvious that *he* understands *us*. It's very fun to be able to communicate more!
I've been told that development isn't necessarily linear, but happens in waves. I think this latest wave may have been spurred by hanging out with his friend Abby this past week. At 3 1/2, she's much more advanced with her language skills, and I think Jake started to catch on :-)
