"Normal" life for Graham?

I've been trying to find special things/ activities for Graham since his world has changed a wee bit with the introduction of Brooks. He went to the Aquarium with dad a couple days ago, and we introduced the "colored bath" concept. Primarily for fun but also to help him with his colors. He can count to ten, he knows most of his letters, but colors seem to still mystify him. Most everything is still green. (So we started with a green bath!) So far Graham seems almost oblivious that someone else has entered his world. He has had great entertainment time from his Papa and Gigi and BB. He is really good buddies with his Papa - loves spending time with his Papa! (He loves spending time with his grandmothers, too!)
