The boys have been enjoying each others' company, which has been fun to watch.
They both love to explore, and really like playing with cars together. Here they are playing hide and seek under the bed.
David now does a good job sitting alone. I should have figured that crawling (and getting into things) would come before he learned to sit. I have a feeling he's going to be high-energy just like his big brother. David has been into EVERYTHING. Nothing is safe anymore, and we're having to really watch what we leave out, since it will quickly be snagged and snacked on by our resident curious crawler.
