So this is the first pregnancy that an ultrasound tech has actually given me the weight of my baby. But I'm not sure how accurate the weights are. Were they accurate for anybody or close to being accurate as of yesterday he was 6 lbs 3 oz and they gain half a pound a week so he'll be 7.5-8 lbs when he's born? My hubby was only 6 lbs and 9 oz and I was 7 lbs 4 oz. My youngest daughter was 7 lbs 2 oz and she was full term and my oldest was 4 lbs 2 oz and she was 9 weeks early (her dad was a bigger baby- he was in between 8 and 9 lbs when he was born).
