The thing with surrogacy, this lady from the sounds has never had a baby before and she has now had a c section. Normally they say 3 max, but case dependent, theoretically one c section and they could tell her there and then to never have more children, she’s more likely to need c sections in the future and she may be able to have like 7 but it’s unlikely due to scarring. I’m assuming people do it because they need the money financially, and it’s horrific infertility but at the same time you are paying someone to put their life at risk and their ability to have future children for themselves!
