FamZoo doesn’t yet have an option for helping kids invest. However, there are instructions in the FAQs about how you can set up a pseudo investment account. You can track your child’s investment gains or losses by adding and subtracting to the account as the market changes.  However, if you want the money to be invested in actual stocks, you’ll need to set that up with an investment firm that offers fractional shares of stock, like Stockpile.
