Need some mommy advise


So my son will be 7mo on the 19th. He is very brave, ambitious, busy, and physically advanced for his age. All of that together means lots of bumps. We have hard wood floors and he is pulling up on EVERYTHING. like I can't turn my back for 2 seconds and his up on something. But he doesn't understand he has to hold on so he just let's go and falls and bangs his head almost every time. Scares me to death. Any ideas on how to allow him to progress with his development but keep him from going to the emergency room. We've out down soft matts and that has helped a tiny bit but not much.
