Not a Baby Anymore

Seems like just overnight Nate is not a baby anymore. Suddenly he seems so old. He is helping me a lot more and his speech is developing. I guess the moment that he is so big is after I picked him up from CMO, I asked him, "Did you have fun at school today, baby?" To this he replied with "baby" and pointed to Maddie. Stealing the paci from Maddie is not an issue anymore either. If he finds it, he either brings it to me or gives it back to her. He's getting a little bossy too, which makes him feel older--now he's telling others what to do, especially his little sister. If she stands up in the tub and I tell her to sit down, so does he, and then he "helps" her sit back down (this is usually grabbing her and pulling her down). He does this as well when it's time for diaper change; he tries to bring her to me. The other night we went out to eat. He sat and colored and played with his cars. He was wonderful. When we got up to leave he grabbed his artwork to take with him (a first). He is also now sitting through an entire book with actual paragraphs. He's always liked his baby books that only have a few words on each page, but his new favorite, Finding Nemo, has to be read to him several times each day. Although he still has A LOT of growing up to do (he still doesn't like to feed himself, etc.) he suddenly seems much older. It's hard to explain, but there's a change there.
