So, when I first made my registry, I put all three of these on.

My guess is that I don't need all of them. For swaddling, I've heard just using regular swaddle blankets that should be enough, but babies can sometimes "break out".

So is the Woombie for newborns and the Halo sleepsack for infants? And the A&A swaddles are just general use?

These are the ones I'm looking at:
