Stuck on a pattern - Sweater armhole

I am knitting a childs sweater and I am on the front and it says to: Bind off 5 sts at beg of next row, then dec at armhole edge, [2sts] once and [1st] twice. It is the left front that I am working on. I got to the bind off done and don’t know what they mean next. This is my first sweater… I have done hats, doll clothes, scarves, blankets. Any help would be appreciated.

Bind off 5 sts at beg of next row, then dec at armhole edge, [2sts] once and [1st] twice.

You bind off those 5 at the beginning of the row–that’s the armhole edge.

Then work a row even.

On the next row, bind off 2 stitches at that same row.

Work a row even.

On the next two right-side rows, bind off one stitch at the armhole edge.

Thank you very much… off to try it so I can get this done before my daughter grows out of it.
