I'm a FTM of a 10 week old and want to start up a savings account for him but despite lots of research I'm confused re the best option. DH and I want to put £100 a month away, plus poss the occasional extra bit here and there. Grandparents will also want to save for him... probably around £1000 per year in total. Primarily I want the money to be locked away til he's 18 and I don't intend to make withdrawals.
Am I best with a junior isa or child savings account? I'm confused about the £100 interest limit with the latter but presumably I wouldn't reach this threshold??
Also is it best for Grandparents to set up a separate account or contribute to the same one??
