I have a dcb who is great all day with me, listens well but the minute mom steps on to pickup, wow!!! He turns into a little crazy hooligan while she waits at the door and does nothing to calm him down. He gets so upset and runs off to the point that I can't even control him and wonder why the heck mom doesn't just grab him and take him home!!! What do I do? She doesn't see it as an issue, just thinks he is being silly meanwhile I want to just say "take your kid and leave already" it makes me look bad as a provider because I honestly cannot control this child because he goes nuts!!!! Help
