we in same boat ours had the halifax high rate accounts that up until last year they just kept restarting them for us at the end of every 12 months. Now they dont and you have to go in with all birth certificates again and open new account. I couldnt be doing with this every 12 months twice a year as they each ahve own account taken out at different times.
So at moment there money is just doing nothing. We heard about the new child isas but they said we have to sign control over to the children so come 18 they would get there money and we would have no say. Which I am not keen on as I know the money is for my children future and have conditions on what it is being saved for and dont just want ti wasting and at 18 who knows wht they will just do with it.
so so far not found anything appropriate need to look this month as my other childs account end soon
