Charlie is 21lb 15 oz (85th percentile) and 29.5 inches (90th percentile). Charlie claps when he is excited and also if you ask him to clap. Charlie waves back and waves when you ask him to some of the time. If Charlie isn't even facing you and you say "I'm going to get you" he will start crawling quickly. If you blow a raspberry Charlie will blow one back. Charlie will let go when he is standing for a couple seconds. He is cruising like crazy.
