Christmas gift for parents

So at the daycare I work at we always do a gift for the parents at the end of the year for Christmas. For my class we’re making snow globe ornaments and I also wanted to do a group picture to send with them. The group picture thing more than likely won’t work as the kids are two. I even tried doing individual pictures of them with the trees we have in the building and they just get too excited and won’t stay still. I just took some other really good pictures of them (individually) in our classroom and they stayed still. So would making a collage of pictures be a great idea or should we just keep trying to make the Christmas pictures?
