My 6 year old (almost 7) son is having a really hard time adjusting to a life with a baby sister. He’s so used to being the only child and the center of our lives and now that my daughter is here (2 weeks old), he’s acting out, getting in trouble at school, won’t hold or even acknowledge her. He’s normally such a well behaved and sweet boy! I’m a little worried. My husband and I prepared him as well as we could’ve! Any tips/ideas on what to do?
