I am expecting #4 in April, and my midwife is suggesting that I change my diet in order to prevent the baby from getting too large. My first 2 girls were both about 8 1/2 lbs, but #3 was 10 lbs 2 oz. She was born at home after a 20 hour labor (much longer than my first 2, but it was also my first without pitocin.) I felt like when we discussed this she was suggesting that my youngest was a "tight fit" baby. I never questioned my ability to birth another large baby up until our conversation, although I wouldn't mind this one being smaller. She just said I should cut out sugars and carbs. It is not so much that I don't want to change my diet, it is just causing me to be really stressed out. I don't feel as trusting of my body to birth my baby. I feel like if I screw up the diet, I will hurt myself or the baby if I birth at home. I know my midwife did not mean to make me feel this way, I will talk to her about it for sure, but now I just feel so much doubt that was not there before. I don't know if that makes any sense, but that is where I am at.
Big babies do run in both mine and my husbands family, both our grandmothers had 12lbers vaginally.
