One fund for long term saving

[justakiwi]

I am thinking about setting up a separate Sharesies account to invest in one fund for my 5 grandkids (combined). I know I could set up kids accounts for them with reduced fees, but to do that I need IDs, parental permission etc etc. I don’t want to do it that way for various reasons. I just want to invest a little each week for them, for the next 10-15 years or more, separate from my own investments. Won’t be telling them about it - will just let it grow and see what happens down the track.

I am thinking USF would probably be the best fund. Comments, feedback, suggestions? Not talking big amounts of money here. Just a way for me to do something for them.
