Buttonholes for baby sweater

#1

Hello-Can someone advise, direct me to where I could find how to make tiny buttonholes for a baby sweater? The pattern I currently have has no buttonholes and I think it really needs them! Thank you

You can usually just do a YO k2tog for a small buttonhole. For a little larger one, k2tog, yo twice, ssk, then do a k1 p1 in the double yo on the next row.
