My friend sent me a care package and included a 123 swaddle blanket. OMG. It's seriously the best thing ever.
Keeps my DS super warm and cozy and he can't break out of the swaddle.

Just thought I'd share. Anyone use this before?

It's SO warm that I've swaddled him in just a diaper and he still stays super warm.
