Your kids and his kids

I think this is depending on their age, but I think you should just be honest with them and say look, there's nothing I can do about what (insert child name) gets elsewhere, just like there's nothing I can do about what you buy with your own money, or what you listen on the radio, or what color socks you wear and if they're teenagers, ask them to be adults about it and don't be ridiculous, because really after about 9 they can understand the concept of you not being able to control other people. Not only that, but you can tell them that they don't have the right to question how you decide to handle things and I think it's okay to put your foot down and demand respect about the situation and no more questions or fits or stupid things like that, because it is stupid and they don't have a right to make your life hard about it. It might be mean, but realistically, when else are they going to have it this good in life? Where they get to act stupid about what someone else gets? They shouldn't do it now either. Remind them how hard you guys work to give them what they have and to be thankful and not greedy. My son acts greedy sometimes and kids have to be told that they don't control things, you do. I know, I'm long winded, lol.
