Also, if posssible, try and have your client have two support people, (you and partner would be ideal) so that partner can go to the warmer to be with the baby and someone can stay at mom's head. I have successfully gotten baby to breastfeed in the OR while mom is being repaired, when mom has wanted it...I will cut and paste here from a post where I described this for our local ican group.
"I am on mom’s left side, at her head. Unwrap baby and place baby facing down over the nipple. Baby’s head is closest to the surgery drape and their feet are hanging over mom’s shoulder, wrapping around toward the back of her neck like a stole! Hold baby’s body with my left forearm, while I hold the head with that same hand. (remember baby is practically laying on mom’s upper chest/shoulder) so it doesn’t roll off, hold the breast with the right hand (this may even end up across mom’s a bit) and attempt to latch. Baby is practically nursing upside down, (they don’t care!) and I cover baby with a warm blanket. I am in pretty tight next to mom, also using my body to keep baby there. Mom can use one hand to stroke the baby.
It is not pretty, and remember I have only done it a handful of times, but it has worked and baby seems pretty happy!"
She should check out ICAN for resources now and afterwards as well.
Good luck to your dear client!
