My DD who turned 4 in May has been bossy since three, but unfortunately, I do not have any advice. One of the main things I am working on with her is to soften her approach with other children and to let others lead or at least take their reluctance to play a certain game with more grace and not try to tell them what to do even more vigorously. She even tries to take over circle time at school. Sorry, no advice, but at least you know you are not alone. Although it may have been hurtful to you when the other mom said your DD was bossy, I wouldn't worry about that label too much: it just means she likes taking charge and is confident. I'd rather have that than a child who didn't have confidence and who could be easily led which could translate to problems as she got older and gave in to peer pressure. Many children go through bossy periods at this age and a gifted child often wants to lead.
