I just spent 20 minutes laying blankets on my daughter's floor

For context, on Christmas evening our 6 1/2 month old daughter flipped our of her crib because we didn't think it was time to lower her mattress. She landed on the carpeted floor, no injuries, just scared.

After putting the mattress on the lowest setting I felt relieved, up until a few days ago when I found her on her knees, holding onto the railing. By then I was still somewhat relaxed since she sleeps in a sleepsack and thought she couldn't get up to stand because of it. Right? WRONG! Baby girl can stand, regardless of the sleepsack.

This left me with one choice for now: baby-proof the floor. So there I was, laying all the blankets and cushions I had at hand, all flat on the floor. All this in super quiet mode since she had just fallen asleep.

I read somewhere that if the top railing reaches her mid chest there is no way she could fall, but they also said there is no way a 6 month old can stand with support, so yeah.

Also, I feel so alone in this. My husband gives me all the support I need and I love him for that, but he is a trucker so we only get him for the holidays and one week every month. I am so scared that she might fall again, although the floor now is so soft it feels like a cloud.

Sorry for the long text, I don't even know the point of this post, but I really needed to get this off my chest. The fear of her falling is eating me alive.
