Knitting again

I’ve recently started knitting again after a 2 year hiatus. Here’s a dumb question. I just want to knit a simple newborn hat on circulars, all the patterns I find don’t call for enough stitches to go around without stretching them too much. Can’t I knIT a baby hat on 16" circulars? I know I’m going to have to go to DPN’s eventually, but…
I know I’ve done this before…

For the size of a newborn hat you’re going to need dpns or use a technique like magic loop or two circulars for just the reason you give. It’s just not enough stitches to go around on the 16" circ for most patterns.

Newborn hats are usually a little less than 16", and while there’s smaller circs, they can be hard to knit with because the needle tips are so short. You can use 2 circulars, or a longer one with the magic loop technique; you can also use single loop with the 16" ones (or from 24-32") to get started.
