Hi, when i saw the midwife my uterus had grown 4 cm in 2 weeks which is alot i know it can stop growing but my bump is bigger also, im only 5ft5 and did weigh 9 stone the good old days. lol but now im 11st 2 pound all my weight is on my stomache i havent put weight anywhere else... the father of the baby is tall and slim too but the baby is about 1 cm and a half bigger than it should be., I unfortunatly smoke which is terrible but i just cant stop due to stresses but it says smoking causes low birth weight.. i just woundered how can some babys be big when parents are small.. my partner when he was born weighed 8pound13 i weighed 7pound11 could it be becuase we were good sized ?
