"well if they have agreed that the mum will be a sahm....then they have 2 kids,always planned a third,but then hubby loses his job....then why should the sahm deferr HER plans?? "
THEIR plans, surely? planning to have a child isnt the sole choice of the mother.
and OP, in this situation YANBU.
disregarding people living in extreme poverty with no access to contraception, and those who conceive and then get made redundant, and all the other situations, because obviously that cant be helped really, and those situations are awful, but lets just look at the one that the op has mentioned.
but planning your children around what you can afford is a very sensible way of being a parent surely?
i mean, i WANT a new car, and i can afford to buy it, but cant afford to maintain it. so wont be getting my lovely shiny new car.
