If your teen becomes secretive and doesn't want to chat even about how her way went in school, should you consider it normal? Why or why not?

Alongwith hormonal changes in children,there come behavioural changes. It is very normal for teenagers to suddenly become quiet an uncommunicative. Give your child the space she requires at the same time try and indulge in friendly conversation to get an insight as to whether all is well or something is troubling her. Let her know you are there for her if she needs you. I have always told my son that if something is wrong or something is troubling him he can always approach me.....even if he has done something wrong and I will always help him out.
