Just wanted to add too that it looks like his first nap is about 3 hours long and his second nap 4.5 hours long. With him being so little yet he should be eating every 3 hours during the day. So if a feeding time comes along and he's sleeping, it's time to wake him. Try keeping those naps no longer than 2 hours. His A time will probably decrease and he'll probably add in another nap, but that's fine.
