Help! i don't know what to do.....

Veronica
So my little Teddy will be 6 months on December 9th. As of last week he has figured out how to sit up on his own and my worry is he does this in the crib but is still falling over a few times. My concern is what can I do to protect him from getting very hurt when he possibly sits up and falls forward!?! 
Anyone else's 6 month old getting into sitting position on their own? How did you deal with the concern of them hitting their heads or faces on the crib? I just want to wrap him up in padding Haha. My anxiety is out of this world now that he is becoming more mobile 😫
Thank you in advance! 💕
