I have two summer birthdays and decided to hold them back. No regrets. Someone told me, do you want to gift your kid an extra year of childhood or an extra year of adulthood? Childhood all the way! I know it’s “getting out of hand” but in Texas it’s been this way for a while. Growing up, I can remember lots of boy in high school who had a spring/summer birthdays - they seemed so immature and were physically smaller!
For girls it’s a different bc they mature faster.
