Congrats! I think I'm holding out another month or so. MIL tries to let him nap without a swaddle and he never stays down long, so I don't think he's ready.
Swaddle for as long as you can! I swaddled my first kid for 9 months. When it came time to take it away, it was no big deal at all. The more practice they get at sleeping, the more they rely on it!
