So I Always Knew

So I always knew that I was pregnant. Maybe even from the day that we laid and created this blessing. But what has really baffled me is the fact that I have a three year old and before any of the test showed up positive, she started rubbing my stomach. When I asked her why she was doing that she simply said that a baby was in there. To make matters even worse, she started back acting like a baby herself. Very independant child all of a sudden acting like an infant. So we went to target and she told me that I needed to get a double stroller for her sister, whom she has already named. And that was the end of that convo. Has this ever occured to anyone else? Toddler sensing a change?
