On the financial side - that was a consideration to some extent. We left the city where DH and I met and moved to one where cost of living was so much lower, and I suspect that if we were still living in the high cost city, we would have struggled with the idea of more than one child. Where we live now, many families here have 2+ kids (our next door neighbors have 4 children and our daycare is full of families with siblings - DS's age group has 4 kids with siblings DD's age and that is just those families with children the same age spacing as us). Our area is really set up for families with children (when we went to visit our former city and went to the area's large Whole Foods market, it was hard to find decent baby food compared to our local supermarket's baby food selection and the area in general felt somewhat unwelcoming to young children when we went around and about).
