I have age gaps of 15 months, 26 months, and 47 minutes. I found 15 months to be the easiest but I could see the advantage in having a larger gap and more time to spend on each child in babyhood. All my children are very close to each other, and they enjoy many of the same activities (making days out and holidays much easier to plan). But it has been hard work, although it is getting easier now.

Personally I chose a small gap as I wanted to minimise the length of time I had a small, very dependant, child. It is my aim to go to university and I wanted to neither delay this for kids, or have a massive gap due to waiting until after my degree and subsequent establishment of my career before continuing having babies. I have friends who have larger gaps in their families and they have spent double the time out of the workforce that I have, so this was my main deciding factor.
