Has anyone else actually felt their baby practice breathing? I was watching him do it at my last ultrasound and noticed my stomach moving with his practice breathing. And now i notice him doing it all the time. The ultrasound tech seemed surprised that he practiced for over an hour while we did the ultrasound between hiccup fits of course. Either way im glad hes practicing so much! For being so tiny (two weeks behind) at least hes keeping up in other areas!
