As a kid, when I asked my parents why there was Father's day and Mother's day but not Son's day or Daughter's day, they answered "every day is Children's day". lol
Kids nowadays are way more witty and worldly than kids half a century ago though... So make sure they understand its a quip, not a challenge to lose trust in parents forever because in 1957 the UN actually declared children's day 😂
