You know, I think it really just depends on the kids and you. And in the end, you just make it work, whichever way.
Personally, with my DS the way he was, anything less than a 2 year gap would have been soooo hard. Now he finally sleeps through (most nights) and does still have a day nap (usually - not today ), and he spends most of his time in his own little fantasy world so it's not too hard to find time to see to DD (or spend time on the computer even). I think it is handy if the older child is toilet trained, can dress themselves and get themselves into the car, etc, and things like that. I'd like a 3-4 year gap to be honest, but we'd like 1 or 2 more and I'm getting on a bit...
Plus I just didn't want to face IVF again before he was 2. We tried naturally for 6 months beforehand too.
