This same thing happened to me and to a friend of mine a couple of months ago. My son is 15 1/2 months right now and my friend's daughter is the same age. I think it is just something they go through at that age. My son started walking at 13 months and my friend's daughter started at 1 year. My son goes to daycare and my friend is home with her daughter. We have two very different situations however I children were doing the same thing. It only lasted three weeks and then it was back to normal. Take comfort in knowing that it will stop and get better. You just have to let her go through it. :) Good luck and I hope this helps.
