How to add a hood to a cardigan pattern?

Hi there, I’m knitting the Sock it To Me baby sweater - (posted alst night about issue with getting sleeves attached, haven’t resolved that, but thinking ahead anyway). I’d love to add a hood. Can anyone point me in the right direction?

Thanks!
Jennifer

You could do the hood from this one. It is worked at similar guage and sizes. Has instructions with pictures, so that may be helpful?
