Buttonhole/Pattern Problems.. Help

The pattern reads to continue with the ribbing for 6 sts then YO. K2tog (rib 8 sts, YO, K2tog) 4 times and then finish the ribbing. I have tried it and it doesn’t seem that the YO, K2tog don’t create a button hole. Am I supposed to work it in there myself? Or should that do it? Help!

On the next row, when you knit the yo stitch, you will see that there is a hole there–that’s the buttonhole.

That buttonhole is sometimes referred to as an eyelet because it’s very small. Not always apparent as it’s being worked. Often used on baby and toddler apparel.
