Children sensing pregnancy


Has anyone had a child sense that they were pregnant before they even knew? I have been TTC for over a year and a half now and this was my first cycle on clomid. I still have 5 days until Aunt Flo is due, this week while on vacation with my husbands family my 4 year old niece looked at me very seriously and said you have a baby in your belly and then walked away. I know she is 4 and I’m trying not to get my hopes up but it gave me a little bit of hope.
