Cr2 stitch

Hi, I’m relatively new to knitting and I have just started to knit a baby hat for my nephew. I have come across a stitch I am unsure of:- Cr2. Can anybody please advise me what this stitch is? Or does anybody have any video links to help me?

It should be defined at the beginning or at the end of your pattern. If it’s from a book, look at the Introduction or Index. What pattern are you following? Can you give us a name or pattern link?
