How often should kids be given what they want, especially small kids between 5 and 8, because it's not easy to break their heart by saying, no!

Maybe if you made them "work" for the things they want, you don't always have to say no and it will instill good qualities like responsibility, hard work and they will learn that things don't come for free. You can make them do simple chores like help you out in the kitchen or help you clean up a little around the house. Giving away things for free at the whims and fancy of kids might end up spoiling them in the long run. Good luck :)
