LIving up to my Expectations?

When Aubrie was a baby, I told Ben she would start walking at 9 months, and she did. I said the boys would walk at 11 months and they did. When Sophia was 8 month old I predicted that she would walk at 15 months. Well, she turns 15 months in 3 days and here she is! I'm beginning to wonder if they were only living up to my expectations! LOL Sophia started walking "short stints" over the past two weeks, but today she started getting up from the ground every time she fell! Now she doesn't want to be held! Ugh!
