Giving your children nice home cooked food, fruit and vegetables they can eat from the bowl whenever they want, nice clothes and shoes and nice uniform (meaning at least 2-3 dresses/trousers and tights, socks etc for the week) all year around. Occasional holidays and days out.
OR
Taking them on holiday every school break, taking them out of school for days out so they have happy memories of going on holidays as children.
I mean what would you spend your money on if you had it? Only one or the other.
