Would he be prepared to do the childcare while you work/study? If so, would that change your view? I agree that it is not the thing to do to bring another child into your family if it is not something that you both want, however, if you think that you will want another at some time, personally, I would have it now so that you can get them both of to school while you are still young enough to pursue an education/career. I would say that if you want to learn to drive, you get that sorted out first, It is not fair to leave you with 3 children and not being able to drive (even if you don't always have access to the car)
