DS used to be the sweetest boy, very well behaved, great manners, kind and caring, just a delight.
He's not long turned 13 and I barely recognise him some days. He's petulant, moody, makes offensive 'jokes', huffs and puffs when you pull him up on stuff, the manners are slipping.
Do they eventually remember all the stuff you've been teaching them for the last decade or is it gone forever? At the moment I feel like I've done a terrible job parenting.
