Hitting my toys

Coco gave Stryker a toy that attaches to his car seat several weeks ago. It has a mirror, frog that plays music & lights up, & turtle that has beads in it; all which spin/flip around. Coco & grandmomma have been working with Stryker on hitting the toys to make them spin/flip around. After only two days, he began doing it on his own. The first time that we noticed it was when Logan & I were riding in his truck. This afternoon, we put Stryker in his car seat to run an errand. He was looking so intensely at his toys. All of a sudden, his little fist started hitting the bottom of the frog. Each hit resulted in Stryker smiling & laughing! It was absolutely adorable. He's beginning to entertain himself with toys. Seeing Stryker figure out he can make something happen means so much.
