Between the two of us we have 3 nieces and 2 nephews (soon to be 3 nephews!!! YAY). Niece #1 (8) is my brothers. Niece #2 (4) & #3 (2) are my husbands. Both nephews (8, 4) are my brother #2s.

We genuinely really love all of them so so very much.

But if I have to be completely honest I/we often find ourselves comparing them.

My niece and nephews are just SO different from the other 2 nieces.
We are constantly amazed at how sweet, motherly and genuinely a good human being niece #1 is. She is only 8 but she has ALWAYS put others before her. Since they are close in age her and my nephews are more like siblings than cousins. She is always taking care of them. If they are sick she will go get them tissues. When they are out and about even when they are not together they always ask if they can get something for the other. Niece #1's mom (my SIL) is currently pregnant and she helps her get out of bed/couch and gives her foot massages! She does this w/o my SIL asking. She is SUCH a sweetheart. I've just never met a kids who cared so much about other people before herself. When I talk to her on the phone she asks me "goo jie (aunt in chinese) are you feeling well?" after she found out I was pregnant.
My nephews too are also such sweethearts and care about other people. Are not selfish. Don't get me wrong they act out like other kids! But you generally only have to ask them once to cut it out and they listen.

My husband's nieces on the other hand are a total different story. They ARE good kids. The older one though is just more selfish. Case in point: when they were all here visiting my mom peeled clementines and oranges for the kids to snack on. She loved the clementines so while she is still eating she takes ALL The clementines off the plate and puts it in front of her. So I ask her A why do you have all the clementines in front of you. She said because I like it. And I said well maybe the other kids like them too and want to eat them as well. She goes but I really like them, they will eat them all.
She's also starting to develop a really bad lying streak. Now, I know all kids go through the lying stage. But she was here for 2 weeks and every single time we caught her in a lie she will refuse to admit it. And adamant that she was NOT lying.
She's starting to also get really conceited. Constantly saying she is the BEST at everything even when she did not know what that thing was!
There were two occasions where she smacked my dog hard and various other occasions where she was really rough with her. The first time she hit her I caught her and told her she should NOT hit dogs. The second time the grandma caught her and she was sent to bed early. And the big trip planned the next day was cancelled because she refused to apologize to my husband and I for hitting our dog. Seriously, if our dog was any less good natured she could have gotten nipped! Our poor dog just stands there when she hugs her rough at the neck and both times that she smacked her! The next day she pretended like she did not know why the trip was cancelled. When we explained to her why she knew what she did was wrong but yet she did not want to apologize! She has been around other dogs. My ILs have 3 dogs and she had a dog when she was younger so she knows it's wrong.
My MIL is really worried about the fact that she hits animals.
I'm more worried about the ego and lying!

I don't know. I feel horrible comparing them all. But maybe because niece #1 and nephews are SO well behaved and such great kids that next to them everything niece #2 does seem so much worse.
The other thing is I/we know where we stand in terms of disciplining my brother's kids. With his brother's kids we do NOT feel comfortable at all disciplining them. There's a line we do not cross.

Sometimes i wonder if we should have told BIL how his daughter behaved when she was here. Rather than say oh she did pretty good. Granted, she was much better this time than she was the last time she was here. I have seen improvements in her tantrums. But they lying and ego really worries me.

Does anyone else (unwillingly) compare their nieces and nephews?? [It makes me feel like a horrible aunt!!!]
