Morning all
My 11 yr old DS has since starting secondary school in September lost the following;
His student Oyster card
School drawstring bag with trainers on the train
Pair of trousers after PE
Jumper
Blazer
Brothers Oyster card he was borrowing until we can replace his own
PE shirt
School access card (which was with original Oyster card)
We tried putting the second Oyster card on an old work lanyard around his neck, but it has still gotten lost!
Before this I told him repeatedly to keep his pass in the zipped inner pocket of his blazer, yet the pass went missing
There is no issue re bullying, rather forgetfulness/ carelessness which is really annoying
School doesn't allow mobile phones, so some parents have brought kids a tracker kids watch which allows parents to contact kids in an emergency but, I had planned to get this for him also, but scared he will just loose this also!
It has already cost me a fortune to replace most of the original kit, but even on Friday the last Oyster card, blazer and jumper went missing and I had to rescue him from the train station after work as otherwise he would have been stranded
I am totally at my wits end and do not know how else to get him to be more careful with his items, so fed up! And thinking of not getting him Christmas presents and using the money to replace school kit instead 
So has anyone else had this experience with their kids and are there any tactics for lessening likelihood of stuff going missing?
