At 50. We have two already and he really wants another one. Ours are late primary / early secondary age. I can't have another myself (nor would I choose to have another now, mid 40s) due to previous medical issues. So, as the mortgage is due to be paid off etc I have suggested he either could look at adoption or fostering, perhaps, and it will fall to him to sort childcare / feeding / nappy changing due to having two children already.
