£10/week?
I’m not that old and remember a Saturday job netting me £20 for 6 hours scrubbing pots! having said that there were always the rich kids at school who got more pocket money than I could earn.
or are you expecting him to start saving for a house deposit?
In all seriousness, I’ve had ‘savings’ from pocket/birthday money since the beginning, always saving up for something. Usually encouraged by my parents going halves on anything necessary or expensive. I got into dinghy sailing so they bought a mirror dinghy, which was then sold and I had to match it’s value to buy a Laser, which was then sold and used to fund a motorbike (it was 19 miles to school).
And I’ve just bought a house, so yup, some of that money was from keeping my room tidy aged 7!
