Help/Advice Please!

Hi all,

Our little guy is currently quitting his dockatot cold turkey (he's teething and the excess drool created a mildew smell that wouldn't come out), and is showing signs of rolling over while swaddled. He hasn't yet, but he's very wriggly. He is almost 4 months old and hasn't rolled over either direction yet.

How did you guys transition your babes from being swaddled into using a sleepsack? I am afraid to go cold turkey, and I don't want to push another transition on him as he's currently adjusting to another one.

Advice?
