This might be a very naive post, but I am concerned about my daughter, who is recently becoming increasingly grumpy, sour and negative. It's not ALL the time, but more and more her responses to me, her mother and brother have such a huffy and gloomy tone. I assume this is not uncommon preteen behaviour, but I guess I would just like to hear from people who are going through a similar thing (so I feel less like I have made some unique and irreversible fuckup) and also from people who have found successful ways of dealing with it and helping their child connect with their more sunny side.
