My first three were three under three, and hopefully my last three will be too!!! I actually regret the big gap between 3 and #4, but couldn't be helped!!(divorce)

I found it great. They are close, went to school just after each other, and got out of nappies sooner!! You really do just adjust. If your going to stay home with the bubs, then I say do it all together, rather than be on and off. I went back to work after #3, so had my "mummy" years, and then back to "work" years. Having a few years off, and just being there for all the bubs was just so great, and the kidlets really benefit.

It all depends on what works for your family unit. But I say go for it.... Not many people regret keeping their family close, but i do regret a big gap.
