Your answer was perfect, but dont project your own concerns and experiences growing up onto her - asking you once does not constitute a ‘preoccupation’. Even if she asks it more times - the answer is yes every time, ‘youre bloody gorgeous, of course you are. Right what are we making for dinner?’
Then of course at other times praise her kindness or her courage or her creativity or her physical abilities or whatever else - and give lots of opportunities to develop and shine in those areas too.
The world is shallow and preoccupied with looks and it’s only getting worse with social media. ‘iPhone/ instagram face’ and an increasingly narrow and artificial range for what is considered acceptable/ attractive. But you not telling your daughter she’s pretty isn’t going to change that - nor is not expecting her to notice it or respond to it.
It’s a minefield and I’m dreading it as my own DD gets older. I’m hoping to take that approach - lots of praise for all the wonderful things about her, lots of support and encouragement for interests and hobbies, lots of exposure to a wide range of people and role models, keeping off social media as long as we can possibly manage. Whether or not it will work remains to be seen.
I grew up feeling not pretty, that my body was ‘wrong’ (fat although looking back I wasn’t, particularly) and less than. No matter how much praise and encouragement I got for being clever, academic, creative, kind etc - that feeling has never really left me and it’s not a legacy I want to pass on to my daughter so I’ll also continue telling her she’s so utterly beautiful, as often as she needs me to.
