6.5 year old cries and cries until he gets whatever my youngest has. Youngest gets so fed up that he gives in. I have schooled the youngest on not having to give up what he has because somebody is crying, it’s his stuff and he shouldn’t have to. Problem is, my oldest can cry for up to 2 hours until the play changes. It’s very challenging, as soon as he gets whatever it is, he stops. I tell him once, you can’t have it, your brother is playing with it and when he is finished you can have a go. He then proceed to demand when that is, we’ve tried timers, doesn’t work, he will then just refuse to give it back and it causes a huge thing. So I stick to my guns but then his little brother gives in. So now everybody has been subject to screaming and tears for 25 minutes and now he’s happy as Larry as my youngest has given in. If I intervene, youngest starts advocating for oldest. What do I do? I’m just stumped
