(As of 10 Sep 2020) there's a new Caleb & Sophia cartoon in which the org puts into the minds of children the idea that celebrating a birthday will cause Jehovah to not want to be your friend anymore.
Can you imagine being 6 years old and thinking god himself is no longer your friend because you blew out a candle on a birthday cake or wished someone a happy birthday?
As bad as all this is, the birthday thing is just one of many JW rules that isnt even supported by scripure.
Watchtower constantly hits new low's. Dashing a child's self esteem or instilling guilt.
