Should a mum tell you something makes you look ugly when you're 5?Watch
Should a mother tell a 5 year old something is ugly on them/ doesn't suit them even if it is the truth? Hurt self-esteem/no confidence or learning to accept the truth from a young age?
I remember how my mother told me I looked like "a freak" because she didn't like my outfit.
If it's something that other kids may tease them about, then I don't see the harm in tactfully telling them (maybe word it a bit better than it makes you look ugly). However, if it's just not to the mothers tastes, then she should just let her kids be kids
