My 9 year old boy frequently acts like a baby and very odd in a socially unacceptable way like a feral child. When leaving his friends he will say “bye friends” in a silly voice. He also was pretending to be a dog eating grass at the park. It’s beyond absurd, his father and I have continually told him acting like this will not make him friends and result in bullying. We are besides ourselves. We do not know what to do to stop this.
