We set up an account for our son when he was born, DH's father got it started with a nice sum. We put in $25 a fortnight I think, would have to check as it's all done direct deposit. DH's father also puts in odd amounts every few weeks I've noticed. Once it gets to a certain amount we put it in a term deposit & keep adding that amount to it when his regular account reaches it. He'll get it when he turns 21. I said 18 but was voted against from the males We also have a moneybox in his room that we put our coins in that also goes in.

Forgot to add that none of us can access the money without signatures from all three of us. This was my thing as I felt very protective of the money for DS' sake when we started it! I am now comfortable with the idea of DH's father having access but don't see the point in changing it now.
