Breathing?

I can feel a rhythmic up and down motion where im 99% positive babys chest is (i can feel her head, and i know she is breech) i feel it on the outside of my belly! You can also kind of see my belly going up and down in that spot.....

I googled it, and it says its her practice breathing? Did any other moms feel this? Im 37.5 and having a C Section in 9 days.
