I had just woken up at 1:30 this morning when I heard Bonnie fall down our whole flight of hardwood stairs

It was a horrible sound and scared me to death. I jumped up and ran to get her. She was shaking just a tiny bit. I put her in bed with me and checked her to see if she seemed hurt but she didn't. This morning before I left for work she was jumping off the bed and running all over!
I'm sure your little one is fine!
