Can my child have a Junior ISA?
Provided that your Child is under 18, resident within the UK and does not already have a Junior ISA or a Child Trust Fund then yes, your child is eligible for the new Junior ISA.
What are the best type of Junior ISAs. A cash or Stocks and Shares?
This all depends on what type of invester you are. Junior Cash ISAs are pretty much like regular children’s savings accounts which pays a fixed annual percentage rate (albeit this tends to be quite a low rate) where as Junior Stocks and Shares ISAs invest in funds, stocks & shares, investments etc instead of money.
Stocks and shares junior isas can potentially provide a bigger return over the medium to long term but carry a higher risk, where as Cash Junior ISAs are vulnerable to the eroding effects of inflation.
