growth scans are notoriously unreliable btw, something like a 20% margin of error either way
there are lots of stories on here of people being told their baby would be 10lb and it being about 6lb
a friend of mine was told they HAD to induce her immediately at 38 weeks because her baby was sooooo big.
she refused. had him at 40 weeks. 8lb.
mine have all had giant heads and were all over 9lb, but all born relatively ok. your tear was prob due to the ventouse. i had the same with my first, thankfully only a 2nd degree tear, but similar situaiton
with my second (larger) baby i had him all naturally at home, no tearing. he had a bigger head too
and the third (and biggest) was born at home too in 45 minutes, and again no tearing
if you and the father are both tall/big then it's like the baby will be. but that's ok... photos are really hard to compare to people i think. so much changes in your body. i looked MASSIVE with ds2, but he was only 4oz bigger than ds1.
i looked smaller with ds3, and he was my biggest at 9lb 11.
