So, I've always had large ears (inherited from both grandads!! Really bad luck!😩) and have been embarrassed and ashamed of them all my life. As a kid I had surgery to pin them back. But that didn't stop them being large... so, I wear my hair in a bob and pretend they're not there! That worked for me - and most people either don't notice or are just being pretty polite. Even my DH has never commented on them. But they're still a real sore point for me.
Anyway, tonight my 5 1/2 year old suddenly looked at me and shouted 'You've got massive ears!'
Then started laughing and trying to get a better look at them. 
He'd obviously never noticed before!
Ha ha indeed!!
I guess it's time to be an adult and face my demons. Any ideas how to handle this? He's at that age where if he spots any weakness he'll use it against me... and I don't want him to grow up thinking he can mock other kids' appearances to get the upper hand! Should I laugh it off or try some other tactic?
