My son has an August 9th birthday.
In his school (pre-school and kindergarten) they celebrated his, and the other summer birthdays, with parties during the last week of the school year.
My birthday is August 10th. As a kid, I was GLAD my birthday didn’t take place during the school year. Having to go to school on my birthday would have totally spoiled the whole day! So they could celebrate other kids’ birthdays in class all they wanted, and I wasn’t jealous. I got to sleep in on my birthday, and not go to school, and that was the best celebration of all!
