Here is one of the designs I have been working on for premature babies. This one fits a little more snug than the others I have made and can be opened up all down the center front and down the legs.
I found these great snaps that are so quick and easy to use and very effective. The grandmother of baby Jared says they are nicer to use than some of those on baby clothes they have bought because they are easier to snap together. If you’re interested in finding them here is a link for the KAM snaps T5.
