7 year old has suddenly become obsessed with how she looks

[jinmiche]

DD7 (turned 7 in June) started to want to dress up in pretty dresses only since January or so and she puts sparkly little pins in her hair and she even puts (kids) lipgloss on all the time. Even her attitute towards others has changed- she would look at other little girls girls who are dressed in t shirts and shorts etc and whisper to me (very loudly) "That girl looks so messy I am prettier aren't I?" It normally makes parents look over at her shaking their heads and I am always apologising to them- I feel as if other parents feel as if I have taught my child to look down on others.
I don't know where she gets this from at all- she only has an brother (17) and she has an iPad that doesn't have Youtube etc just kids games like Hello Kitty etc.
At first I thought it was just a phase but I feel as if it is getting worse. I have told her over and over again that she must not be rude to others (I never shouted at or hit her though) but she uses the excuse "Mummy you told me to never tell lies"🙄
Anyone else has a little girl like this? Could she be copying the older girls behaviour from school?

Don't tell her never to tell lies. Lies are absolutely essential to being able to interact with others. What if she said to grandma,'Your new haircut is awful'? She has to know that nobody will thank her for telling the truth across a variety of social situations.

What do you do when she says these things?

My ds says ‘you always tell me to tell the truth’ when he’s being cheeky and gets called out in it.
It hasn’t spring from nowhere, is she watching stuff on tv that gives her these ideas?
She needs telling off when she’s not kind about other kids. Obviously you don’t need to shout or hit, does that need saying?!
I was pretty aware of how I looked at a young age. My mum would just cut me down to size with a snippy remark. Next time she’s says she’s prettier, I’d be inclined to say beauty comes in all forms but good manners are much more important.

I taught mine that it’s my polite to make personal comments about others.
If she does then she should be apologizing to the child/parents. Not you.
I think you need to knock it on the head and make it clear it isn’t acceptable.
