So I have a stubborn child... What more could I expect!

My kid is stubborn. It took almost 20 mins to find the heartbeat. The little bugger kept moving around and away from the doppler. But the heart is beating strong 150 beats per minutes. They said he is growing good. Funny how the Dr kept saying he and little boy??? Hmmmm do they know something I dont from the last ultrasound? Or maybe she just says he because it sounds better than it. Guess I will know in 4 weeks when I go get another ultrasound
