what is this little baby doing?

Tyree`sMommy💕 • Hello! I`m Raqueal and I`m a Grad student🎓 and first time mother to a 11 month baby boy 😍
I'm currently 6 months pregnant with a baby boy, I've recently notice that when I lay on my side, either side my baby will come over to the side I'm laying on, ball up and start kicking me really hard 😂😂. Idk what this means? Is he playing or he really wants me to find a different position? Has this happened to any of u? Just curious
