To be at home alone? My ds is 12, nearly 13 and recently he has been walking home from school and letting himself in with a key. He's at home alone for about 45 mins before either me or dh get home from work. Is this unreasonable? Ds is very sensible and tbh just plonks himself in front of the TV until we get back. Someone at work said they thought it was too young and now I'm doubting whether or not I should be allowing this
