Incorrect ... you NEVER put a dependent's W-2 on the parent's return ... it must go on the dependent's return if they either are required to file or they file (as a dependent) just to get back any fed/state withholding they are eligible for. Only the dependent's interest, dividends & cap gains on a 1099-DIV can be elected to be reported on the parent's return to avoid having to file a child's return (which is usually not advantageous).
