DS is 8 weeks old. We currently use Ergo Swaddlers:

However, the way it secures is velcro. And after many washings, and DS getting stronger, he is able to break out. The velcro isn't as sticky these days! Also, if he cries for more than a few minutes, he is a sweaty mess.

I know most babies are done with their swaddles around 4 months, do you think it's worth it to get a different swaddle? I was thinking one of the lighter weight woombies. He loves to have his fists right under his chin. I know they aren't that expensive but I hate wasting money. Thoughts?
