My DD was born via emergency c-section at 36 +5 as my placenta has started to calcify. She was born healthy but small. Her Apgars were 9 and 10 and she didn't need to go into special care at all. However- she suffered severe silent reflux for the first 6 months of life and the doc put it down to her stomach valve being under developed due to premature birth. We also had A LOT of trouble breast feeding as she had no suck reflex at all.

I don't have any experience with induction but my c-section experience was fine. I got skin to skin and bub with me in recovery. I would guess that they will be concerned about what is going on with SIl's health and can't run tests ect while she is pregnant. Neurological issues can happen quickly and there may be a big difference in getting her diagnosed earlier (even if only 3 weeks earlier)
