Would we be crazy to have such a large age gap (would be nearly 6 years) between the youngest of my first three and a baby? I had three kids under 4, so they are all very close together; would a baby be left out? Would I resent having to do primary school then high school all over again with another one, when the first three will be well through it. And finally, I would be 44! What do you think? We've always really wanted a fourth, but were just trying to be sensible, but now it feels like our time to make this decision is almost up....
