Personally I would do it for my sister 100% if she couldn't carry her own but I would only do it after I had my own, imagine one day longing to have a family of your own but it hasn't happened for you yet and the first baby you carry is not yours, maybe she never wants kids of her own and that's why she doesn't mindI’m sure they did do counseling etc and that it’s all clear, but to be honest no one knows how they will feel after their birth. The physical side if it’s a tough one and recovery, mentally with the hormones etc. the fact she’s never experienced pregnancy/birth it’s hard to know how you’ll feel. Most surrogates are strangers and won’t grow up with the child around. She’s a stronger woman than me, I don’t think I could do it, even for family. She’s amazing to gift this to them.
