some relatives try to be the favourite relative, a good way to be the #1 in a childs eyes, is to bring toys or gifts just for them, it makes those kids more likely to want to be nice to or do what that relativise wants them to do when their a bit older.
my favourite uncle used to take my brother an I out for the day to give mum n dad a break, while out, he would let us pick out any one toy, of any value, and he would buy it for us, mum and dad would say he spoiled us, and to make sure we behave and thank him properly for the gifts, of course our overwhelming excitement once we got our dream toy, was usually enough to make him happy, since we just raved on about him for months later.
he also had his own kids and had only just become an empty nester, he had plenty of other nieces and nephews but only spoiled us, and we lived miles away from his family and friends.
we think the logic was, he could see them whenever he wanted, but only saw us once or twice a year, so he used gifts to try and make up for that, no other uncles or aunties came to visit.
