How to prevent jealousy between children on Christmas?

Hey everyone. I'm not totally sure if this is the appropriate sub to post this question in, but this is bothering me a lot.We had a lot of unexpected family emergencies come up and other expensive things that needed to be paid off. And they didn't have much extra to get any toys or games for my brother (10) and sister (13). Parents had just enough to get them some nice clothes and shoes and school supplies. I told my parent's that that is perfectly fine especially with how they have behaved lately. And they agreed. My siblings understood that and apologized for being horrible at school and at home.But the problem is that my uncle(s) went all out on my cousins buying them all sorts of expensive gifts and clothes and things of that nature. And my sister is fine with it because her godparents are spoiling her as usual. But my brother feels a little left out and sad that he didn't get what he really really wanted and I feel terrible. I wish I could help him feel better but I (19) don't have a job or any money to buy him something. He has been really sad these past few days and my dad cried because he worked so hard to make this year special for us but he feels like he failed us.My brother just told my mom earlier that he will be angry and break everyone's things if he doesn't like his presents. That sentence alone made me angry and my parents just let him talk to them that way. So Anyway, I just really wanted to ask someone other than a family member for advice. What can we tell the kids in order to help them understand the situation and to not be so mean about it to my parents? via /r/Parenting http://ift.tt/2hiNTOn
