What sizes to put on baby registry?

Kayla

I already have some new born but nowhere near what I’ll need I don’t think. Like maybe 5 little outfits and couple of little onesies and sleepers. I’m just wonder what sizes to put on my registry? NB? 3M? 6M?

And how many of each? Like, I have no idea how long babies typically wear these sizes and how many ill need of each size.
