It certainly took me long enough but the sleep sack 2.0 is finally finished. Thanks to all the pattern revisions it turned out really great and is a perfect 0-6 month size. Baby S still likes to be swaddled to sleep so she will probably be 3 months old when I actually start using it, however if I were to have put her in it in the super early days I think the waistband still would have been a little loose. I have been debating adding a drawstring to the waistband to tighten it up... what do you think? If I anchored it at the back securely would it still be safe for a baby?
