Working on tummy time with Cohen!!

I have been really trying to do as much tummy time as I can squeeze in with Cohen. I can't leave him on the floor when Corbin is around because he is so rough. Now, Caroline will sit down and play for a long time with Cohen and play mommy. She has gotten really good at wiping up spit up. As you can tell, Cohen isn't much a fan. Slowly but surely maybe he will like it.
