You can efile up to 5 federal returns for free and mail in any others. There is a fee to efile each and every state return if you could efile the federal return... state efile fee is currently $20 but goes up in March.
If you have more than 5 returns to file then for the simple kid returns you can either mail them in or use one of the IRS FREE FILE options or if they qualify use the IRS DIRECT file option both to open up later this month.
