IDK! I guess. Most drs want u to have a csection if ir baby is that big tho. To prevent tearing all the way back to. But if u and baby are fine good. I know one girl who had an 11lb baby and pushing him out broke his shoulder and tore mom so bad she needed two blood transfusions.
I get the same reaction when i tell people i have had 2 over 9lb babies drug free, 1 at home. I honestly don't think baby size has much to do with how hard labor/birth is. My 9lb 11oz baby was actually easier to push out than my 7lb11oz one. And my youngest one (9.1) that was born at home, i didn't even have to consciously push, i just let my body do it's thing and only thought about it and tried to do it slowly while he was crowning so i wouldn't tear, which i didn't with any of my kids.
