Question: isn't the Brewer Diet to avoid LOW birthweight infants and pre-e, essentially by helping the placenta grow as well as possible, thus giving optimal conditions for fetal growth?
Now, I only have my own history to go off of, but my Brewer Diet babies were pretty much 2-3 lbs heavier than my non Brewer Diet babies with gestational ages not really accounting for the difference in size, same father of baby, etc. And both my Brewer Diet babies had shoulder dystocia. Eating normally, I grew a 7 lb 12 oz and 8 lb 2 ozer. On Brewer Diet, I grew 10 lbs 2 oz and 11 lbs even. And I had no GD with any of those babies. The only difference diet wise was normal eating versus Brewer Diet with the Brewer babies being significantly larger and with very large frame sizes (including 17 1/2 inch shoulder measurements.)
Now, I'm following twin diet guidelines for this current twin pregnancy, but I feel like the Brewer Diet is itself an intervention and that it may not be appropriate for everyone. If you put everyone on a bell curve, you're going to have most people in the middle, and a few outliers on both ends. For the people who would normally have very low birthweight babies, Brewer could make a tremendously positive difference in their outcomes. As it's difficult to predict who is going to normally grow a low birthweight infant, it makes sense to make a general recommendation for Brewer's because most people will not be negatively impacted by a baby who is 1 to 1 1/2 lbs heavier, and the people who would generally grow very small infants will benefit tremendously.
But for people at the other extreme of the bell curve, the ones who will grow 8-9-10 lbers without diet modification, I think it could make a difference in a negative way. I sort of wonder if when you've got maybe a very hospitable endometrium, your body naturally grows placentas the same way the Brewer Diet is supposed to. Is there too much of a good thing, though? I don't know, but I am inclined to think so and will not be doing the Brewer diet again. That said, I will also be carefully watching and avoiding any bad carbs that could make for sugar babies.
And to the OP, I do not think you are being foolish. I remember your story, and I've had two dystocias myself in the 2 1/2 to 3 minute range including an Apgar of 0 due to my daughter turtling on her nuchal cord x2. I stay home because I don't want oxygen compromise going into a possible dystocia, and a pit induction DOES threaten oxygen compromise. I stay home because when nurses and doctors are used to c-sectioning for a too big 8 1/2 to 9 lber, I do not trust that they will necessarily know what to do when an 11 lber is stuck. And if you get to pushing with your doctor out of the hospital, you will have whoever is available on the floor. Panic is dangerous with dystocias, and a nervous caregiver CAN do damage. Outside of a c-section, there is nothing better that the hospital can offer you, and many typical hospital protocols will make resolving a dystocia successfully more difficult.
I strongly encourage you to do the research yourself, because knowing what you're looking at can give you a sense of peace. I've spent a lot of time thinking, praying, and reading to reach the positions that I feel comfortable with. I think I'm just going to have higher risk deliveries, period, and that not every higher risk scenario does better in a hospital set up. For my particular complications, the outcomes can be worse in a hospital. So, I will avoid a hospital unless there is a particular indication that makes me think the complication I'm facing is best handled in a medical/surgical setting.
