How do you tell someone their child looks weird without hurting their feelings?

It is not appropriate to tell someone that their child looks “weird” or anything else negative about their appearance. It is important to remember that children are sensitive and their self-esteem can be easily affected by negative comments about their appearance.
Instead of making negative comments about a child’s appearance, try to focus on positive qualities and traits that the child possesses. For example, you could say something like, “Your child is so creative and imaginative,” or “Your child is so kind and thoughtful.”
If you are concerned about the child’s appearance for medical reasons, it may be more appropriate to express your concerns to the child’s parent in a compassionate and empathetic way. You could say something like, “I noticed that your child’s eye seems to be turning inward. Have you considered having them see an eye doctor to check for any issues?”
Overall, it is important to be kind and respectful when speaking about children and to focus on their positive qualities and strengths rather than any perceived flaws or weaknesses.
