Well... my oldest (4 1/2 years old) was wrong.
Since we told him that he would be getting a new brother or sister in September, he has been telling me that there are at least TWO babies in my belly. Some days he’d tell me there were 3 or 4 in there.
Today was my first OB appointment with full ultrasound. Only one very wiggly baby at 9 weeks 1 day gestation. When I told him after pre-school he cried and said it’s not fair he wanted two sisters in September!

Now we shall see if he is correct on the boy/girl question when we get the Verify test done in a week or two.
