Unashamedly inspired by the thread about how kids pay for things.
How much money could your child or children spend tomorrow and how old are they?
So not money that is in a child ISA or other kind of account they have limited or no access to but money they could go online or into a shop and spend right now.
And being as it's only fair to share - my 15 year old has about £1000 in a current and linked instant access savings account (I think - I don't know the exact amount)
