Most of the posts i have read on MN about tears (mainly 3rd degree) happen because baby has come out with their hand/arm up by there face.
Every scan ive had, my baby had been covering there face with their arm, and im starting to panic a little that this is how shes comfy and has decided to stay! Shes also measuring on the highest end of the scale and following her line well, so im in for a bigger baby than my first (who i had at 37 weeks and was 6lb 4oz).
So do i brace myself for a tear? 
Anyone else have super hero babies and how did your births turn out?
