Will she become a nightmare teen??

[Rosewinesummer]

7yr old dd is an absolute delight and always has been. Easy baby and toddler, no tantrums, no issues, all lovely. I have 2 older boys, equally lovely, but for some reason I worry more about dd becoming a teenager and whether she will turn into an absolute horror. Have I just been lucky so far and once she reaches puberty it will all change? Hopefully she's still a few years off any of that but just wondered if anyone else had a lovely child, particularly girls, who remained a lovely teen? No particular reason why I'm thinking this atm just some threads on here about their teenager problems gets me thinking....

My daughter was a lovely child and has been a lovely teen, she is now 17 and still lovely.
She was a very easygoing and chilled child, very happy to do anything and really nice to be around, she has grown in confidence as she went through her teens and is now still very easygoing and is funny and very kind, she always had good reports from school, works very hard and has always a nice bunch of friends.

There was obviously times where she was having a hard time, she would be quite emotional when she was hormonal and would get stressed over homework but she was never rude or unpleasant or anything. Not all teenagers are, some are grand all the way through.
