In my family it's me- 19, my sister- 17, my brother- 15.. that's a nice age gap, close in age but we were old enough that we were out of diapers & the crib by the time the next baby came around LOL.
I don't think I want another baby. If I go for another.. maybe when Elyse is 4 or 5. Even though I don't like the idea of the big-ish age gap, I won't be ready again for a long time.
