Dalton getting mad

Dalton gets mad when he uses his legs. He can be on my shoulder and he uses his legs to push his feet against my lap or stomach..whichever he can reach. He does this on his own and gets so mad! It's like he's saying, "I know I've got to use these legs someday, I just don't want to now! Wahhhh!" He also does this during his "tummy time" sessions. Here's a video from a few days ago.
