So, the Summer Infant Velcro swaddles have worked pretty well for us until this point. LO is 5.5 weeks (but shy of 8 lbs) and now is able to slip his hands through the holes/gaps and bust out, which I think wakes himself up/makes it more difficult for him to fall asleep because he tries to play houdini for a while before sleep. He's wearing the size S/M and they fit everywhere else and technically with the weight allocation should still be able to wear it. But, wondering if we should move up to size L so he won't be able to bust out?

If you used these swaddles did your LO ever use a size L?
