I agree, you cannot directly switch to a child frame. Also, make sure to switch to the defaultContent (driver.switchTo.defaultContent) every time you want to switch frame. With regard to your example, driver.switchTo().frame("mainFrame.0.child") --- this could also work, but you need to get rid of unnecessary quotation marks.
