Are you doing all your presents at your Mums? I ask because if its just a few cant you all agree just to bring a couple of pressies for each child there? Whilst I don't think it's fair for one child to have one or two pressies, and others to have heaps, I was taught from a young age that different things cost different amounts, so whilst I may not have as many, there could be similar dollar value..... Depending on the age of all the kids, they may understand that...
