Childrens pocket money and savings

[Lockdownbear]

I need to sort DSs money, he's 10.
He started with a RBS account in trust, interest is poor and is more suited to a pocket money account.
I'm thinking about giving him control of that account to encourage him to saving and when he turns 11 he could get a card for it.
Does that make sense or am I better to use GoHenry or similar?

I he also has money in Nationwide that I moved to get better interest but it's still not great. I'm thinking I might be better to put that into my name to get better interest and keeps me in control. I know MN has the view 18 is adult but we all know 18 yos can be a bit daft and blow free money on crap.

My son is only two but I'm trying to cover all bases.

I've set up a JISA and pay in £10pm for him, plus any money from relatives. I've also put a small lump sum into a stocks and shares ISA for him as I figure it's got a long time to potentially grow, but don't want to risk too much of his money.

When he gets a little older I'll set up a regular savings account that we can access together while he's a child. Probably in my name so I can balance any gifts between this and the ISAs so he can't blow everything at 18.

I don't have a lot of spare cash and wish I could invest more for him now but I'm hoping it is enough to give him a start.

To teach how to handle money, we have the Gimi app for dd10. Will likely switch to a formal account when she’s 13
