I am so glad she's ok, but don't take chances. Buy two or three baby gates if you have to. They don't realize the dangers. I have several baby gates. If I'm steaming and polishing the dining room and kitchen floor, I use two baby gates to keep them in the LR. One going in the entry way and the other going into the LR. I do this too if anyone comes with a toddler. I don't want to change my girls knocking them over or the toddler to pull hair or ears.
I've also done this to separate my granddogs from my girls if the granddogs get too rambunctious. I also put up 4 baby gates to the bedrooms when a few of my boys and their family come to visit so my girls don't get nosy and either roll in their clothes/suitcase or find some of the kids candies to eat. One time Zada found a pkg. of gum in my sons back pack and ate paper and all. That was when all the gates went up.
