Do you make your older children watch your little ones?
Who do you think you are snatching their childhood away like that? If you couldn't afford to hire a babysitter to watch your kids, you shouldn't have had them. Those kids are YOUR responsibiity, not the older kids. It's not fair that John can't go play Basketball because you have to be at work at 5pm. Find a babysitter that you can pay and let John have his childhood! That is all I have to say!
