we have 3 year gaps with my lot and I love it, as a 3 yr old is normally TT and sleeps well and has own bed, no more waking in the night... But saying that I didnt have a choice as we didnt use anything between babies and this is just the way my body does the gaps...

I can see pro's and con's for all age gaps, when they are big like mine you are over the baby part so while preg you kinda freak out a bit wondering if you can do it all again lol, while with the smaller gaps your still doing all the baby stuff so the newborn just slips right into the rotine...

But with the bigger gap you have the older children who are old enough to entertain themselves while you deal with a newborn and morningsickness while PG and are always very willing to get nappys and so forth, while with smaller gaps you have basicly 2 babies...

Not that any of this will help your decion best of luck with whatever you decide....
