Importantly, the housing market now assumes that two people will be contributing to a mortgage, which makes having one of you take significant time off to look after a child (or spending a very significant percentage of your income on childcare) tricky, to say the least.

One kid was doable for us. Two kids really stretched things and basically destroyed our savings (2 kids both costing £1k a month in nursery fees was not sustainable). A third kid would have meant either moving to a much cheaper house or some other significant financial compromise.
