How long is everyone waiting?

Georgia
How long is everyone waiting to have another baby, if they want another?
Me and my SO have already decided that we'd like another, our daughter is 4 weeks old today. 
Can I get some ideas of how long everyone is waiting? Obviously we haven't had sex yet and won't until after my 6 week postpartum check up, I do plan on going on the pill for a while as well!
