I don't know, I am eternally grateful to IVF as its allowed me to experience motherhood and without it, I may well have remained childless. But to use IVF in a woman who is not able to have children because of her age, not because of infertility/other medical reasons seems a bit 'not right'. I mean, she's not 40 or 50, she's 63. Able to collect her pension in two years time. I'm almost 38 and some days feel exhausted rushing around after a toddler. Could I do it at 63? I very much doubt it.
I don't doubt the child will be loved but I feel quite sorry for them, especially if they are an only child. They could be completely on their own by the age of 20 with no family support whatsoever. And yes, I get that grandparents sometimes have to raise children due to accidents/addictions/deaths but these people have chosen to become parents at this age. Grandparents in those situations don't usually have a choice, they are stepping in due to necessity and to keep their grandkids out of care/foster homes.
