My 12 yr old has started to lie about things and we both feel we cant trust anything hes saying. He was in trouble last wk part of which was lying and he denied for about an hr tben truth came out and then it happened again tonight over something so stupid , i just new he was lying n I was not giving in and then i caught him out. We dont know what to do now, we sat him down last week and chatted to him and hes just not getting it and we dont know what to do now. Can anyone offer some advice please, hes the oldest of 3 so this is all new to us. Thanks
