To a certain extent children are as expensive as you choose to make them - and 'having more' or not is about weighing-up your priorities - honestly - and being happy about what you decide to do. Many people would easily be able to 'afford' more if they decided to forgo the luxuries of that swish newer car, brand-new baby paraphernalia, giant television with permanent Sky subscription, private education, holidays, one magically themed bedroom per child, piano and flute lessons - or swallowed their pride and moving somewhere cheaper with more space.
