He wears 9-12 month old clothes. He likes to crawl all over us and attack our arms like a zombie. Luka and Sheena now come to him, lay down, and want him to pet them. He sits up great. Still frustrated about crawling. Prefers to be in a standing position. He loves Pancake Manor and Yo Gabba Gabba. Loves to watch the traffic go by or go out back and look at the trees and flowers. He is easy during the day, falls asleep easily and without rocking. His nights are getting better. He's a big boy, a definite bruiser. Love love love.
