Put your feelings about this aside, this is not about you. Help your child to blend in. Don't be that mum and son that everyone is laughing about
No, teachers don’t laugh about children, and most parents wouldn’t either. So you let bullies (mums or older children) dictate your children’s lives, do you? They have to blend in - how? dyeing their hair? not wearing their glasses? not mentioning they have two mums?
The sheer amount of women here pressuring the OP under the threat of bullying is shocking: Do you want him to be bullied?, Is your son a girl - no, then don’t let him wear the shorts All the children will bully him and he’ll have no friends and it will all be your fault Everyone will laugh at him blah blah 🙄 Just admit the conservative views are yours.
And no, everyone won’t laugh at him - because he’ll be wearing a perfectly innocuous pair of blue shorts! I doubt any of the other 4 and 5yr olds will even notice.
