My heart sank with each of these posts. I didn't want to keep reading but I think it's best because I've learned about some accidents that never occured to me that could happen. Sasha jumped off my balcomy one time. Fortunately there was shrubbery right below it so it padded her fall. I ran out of the door hysterically but thankfully she was ok. She's 7 months and almost 6 pounds now but I still get nervous when she jumps off of the couch. Sometimes she likes to charge before jumping on the couch and she doesn't always make it and will slam face first into the bottom of it. I just said to my bf recently that I hope she doesn't get a concussion doing that. And to read that someone's baby died of a concussion just really freaked me out.
