Sleep sack

We were swaddling until about a month ago, and then my little seemed to break out no matter what we did... so we’ve been using the merlin sleep suit since then. He is doing well, but I want to go ahead and start thinking about which sleep sack I want to use when he starts rolling over which I’m sure will be soon! He seems to do well with something that has a little weight and/or restriction because he throws his legs in the air and that wakes him up. Any suggestions would be greatly appreciated!! 🤗
