If we waited until we could afford to live on 1 income for 6 years (that's if we only have 1 child) we'd never have kids.
We can afford to have a child. We just can't afford not to work and have a child at the same time. We don't live extravagantly. We don't own lots of expensive toys. We both drive used cars. We don't take expensive vacations. If we're lucky we get back to Ireland every other year to see his parents.
But we do need 2 incomes. Perhaps this lady is in the same boat.
Sounds like you need to move some place with a lower cost of living.
