Did you aim for the same age difference between 2 and 3, as the one between 1 and 2?

If you decided on a different age gap, what factors played in?

My girls are almost 4 (in September) and 18 months. They're 2 years, 3 months apart.

If we started ttc right now, the age gap between 2 and 3 would be the same as between my girls now.
