Why is it awful? Bad behavior has no age limits. I have eleven-going-on-twelve grandchildren. There are two that I can’t stand being in the same room with, and they’re only eight years old. Perhaps they’ll grow out of whatever causes them to act as they do, but for now they’re both just miserable little shits, and have been that way since they were old enough to walk.
I have two nieces and love them equally.
They are very different in personality and at times I am closer to or get along with one better than the other.
Having a favorite or loving one more than the other? Unthinkable.
I have one niece and one nephew and I love them equally but differently.
Hell yes! My niece is totally attached to my SO and my nephew loves,me. So naturally my nephew is my favorite!
I have a niece and two nephews, and I can’t really say I have a favorite. The eldest nephew reminds me a lot of his dad, and because he’s the oldest by several years, I have an easier time having more adult conversations and such with him, he also seems to have a good deal of respect for me, so it’s generally fun. My niece is adorable, and of course since she’s the only girl in the family, she’s got her special place just because of that, she is the clear favorite of several, particularly her mom and her maternal grandmother, who make no attempts to even disguise it. And my youngest nephew, he reminds me a lot of how I was at his, both how I remember myself and how I’ve been told by others, so I can definitely relate to him, even though he’s only 4. He seems to get the least attention of all of them, so I try to give him a bit more, playing trains or whatever. So, looking at them, there’s definitely things I like or don’t about each of them, but that’s how it is with family and people in general. Still, I try to love them as I think they need from me, and I can’t really discernably say I have one that is a favorite over the others.
That said, I don’t think there’s anything inherently wrong with having a favorite. Like with all family, there’s always going to be some I relate to better and enjoy time with more than others, or I just simply spend more time with them. I can definitely say I have favorite aunts/uncles and favorite cousins, so perhaps as they get older I’ll develop a closer relationship with one of them than with the others and then I may have a favorite. That said, I think it’s important to still make an effort to be fair to them, and love them, without regard to how much you may or may not relate to them personally.
I have 3 and 5 grands and every last member of my family can name my two favorites.
It is one of many reasons I don’t play poker with my family members.
I have two nephews. One is 13 and is my brother’s kid. The other is 22 and is my brother-in-law’s kid. The younger of the two is my favorite as we have shared interests and similar senses of humor. The older is a very smart , personable, and handsome young man; but his all-consuming interests at this point are bodybuilding, college, and pussy…all three were of tremendous importance to me at his age, too, but they aren’t activities we can really share. It probably is also a factor that I have known the younger since he was born, but didn’t meet the older until he was already in his teens.
I’m a long distance aunt. I see my nephew and nieces at Christmas and maybe one other time during the year, and that’s about it. So they don’t know me that well, and I don’t really know them. Yet. I mean, they are still kids for the most part. Their personalities are still being formed.
I care about them and enjoy being around them. And I have my favorite. She doesn’t know she’s my favorite, though, and she probably wouldn’t consider me her favorite aunt. But I like her the most because out of the whole lot, she’s the most like me. She totally has my DNA, and that’s kind of cool.
If my twin has a kid, I know she/he will have a special place in my heart.
I have 12 nieces and nephews (ages 12-42) and five greats (11-18). Only four have ever been local to me, so I actually know them better. Two of them are in the same age range as the stepchildren that I raised, so there were a lot of overnights and weekends spent together. The one niece is actually my favorite. She is intelligent, quirky, strong and has a heart of gold (but don’t ever piss her off 
).
I think Jess knows she’s my favorite. 
My husband and I have three nephews and two nieces. I only have one niece on my side, and she does have a special place in my heart. She’s a really cool kid.
I like kids much better once they reach 5 or 6 and you can actually talk with them. My youngest nephew (3 yrs old) is a nightmare, but I know eventually he will grow out of his stubborn, way-too-attached-to-mommy phase.
While I love them all equally, I do click with two of my nieces much more strongly than I do with my other two + my lone nephew.
I don’t have a favorite, but I have a nephew I don’t much like. Males on my side of the family are pretty much worshiped, so being the only grandson, he’s obviously God’s gift. But the little turd can’t be bothered to say hello to anyone or thank anyone for gifts or even ask for favors on his own - he has his mother do it for him. My mother excuses him because “that’s just the way he is” and mostly because he’s the male.
My two nephews are brothers, and less than 2 years apart. Who is my favorite depends on the trip. Vaguely, I am slightly more interested in my godson, the youngest nephew. He is also the most daring and independent of the two, but it is possible that as they grow, this changes. I adored the oldest one when, the last time I saw him, he realized I knew how to play video games and went after me so I could play his games.
I’ve two nephews and a niece, all children of my brother and under 12. Number One Nephew has always shared similar interests and outlook to me growing up, so he’s good even though he can be a bit sly and conniving. Number Two Nephew is boisterous and rowdy but doesn’t complain much and is really just happy to get some attention, so he’s good too. Niece is wants to be a princess when she grows up, which apparently means she gets to be bossy, but she’s cute and sweet, so she gets away with it. I don’t like one more than the other, although my relationship is different with each of them.
And, while typing, I got an invite to Number Two Nephew’s birthday party. He’s actually the worst to buy for, because he has no demands! How’m I supposed to be the cool uncle who gets the best gifts if he’s okay with any ol’ thing?
None I would call a favorite, but there is a niece I despise.
