How do you stop your sim baby from crying on sims 1

I gave my Family 5 babies!
1st) feed the baby
2nd) play with the baby
3rd) sing to the baby
if all else fails...keep repeating. I know its a drag to have to keep your sims happy long enough to care for the babies so type in: move_objects on and then delete your sim. go back to the page where you click on the icon and click it and it'll re-appear with almost full bars!! GOOD LUCK!
