Are there any guides for setting up multiple long term investment accounts (i.e. per child) in M1? (Or any more general M1 guides?)

i don't recommend doing one per child (a financial plan should let you properly create a financial plan that has the desired distributions per child without the need to maintain the heachade of separate accounts and also introduce possibly giving different children different benefits based on unforuntate market timing) are you asking for a link for how to open an account on m1? they have a lot of articles on their site but you can also DM me with questions.

Thank you. My motivation for one per child is that my children give me their own money to put away for them. I'd like to be able to show them an actual representation of their money, on a UI that cleanly mirrors "their" funds, and not simply show them a larger fund and tell them what percentage is theirs.

oh yeah gotcha, just in m1 you can click open another brokerage account then

Unless you have a different approach toward that? I.e. the goal is partly educational.

no i think your's makes sense

Thank you!
