Nope, I dont add to their CTC. Mainly because when they get full access to it when they are 18, and from experience its too young to be given a large amount of money.
I put £10 in each of their normal bank accounts each month, and my mum does the same. Any extra money, such as birthdays, etc. goes into their normal accounts.
When they are a little older, I will probably remove most of this money and put it into an account in my name so that they cant blow it. I will leave them with a nominal amount so that they can spend as they wish.
The rest that I have moved will be for something big, eg. car, house deposit, etc.
