hi just wondering if anyone has any ideas what may be the issue with my DS

he is 4.5 turning 5 has slight speech problems and saw a speech therapist when younger,it seems like the only time he behaves and is quiet is when he is in fornt of the tv...he runs around the house alot and is always jumping of tables etc and has been a climber since he could walk.....

whenever he knows were asleep/not looking he is a total pita climbs in the kitchn and grabs things he knows he shouldnt..just in the last week he good some smelly body mouisteriser and put it all over his room and got the pepper cracker and put that all over his room, ripped all the fluff out off a pillow so i had to sit at his door to make sure he cleaned it or he wouldnt,i put the vacuum in there and told him he could do it when he finished picking up the rubish(ripped paper from books /cardboard) and i go to the loo to find him standing there vacuuming weeing on the floor...

this is not th first time i have caught him weeing on the floor either he will just walk out the room and pee in his room or dining room on the floor or he will do poo on his floor and play with his toys in it.

he has broken 3 single bed frames because he always takes the matress off,even tried tieing it on, and turns them over and jumps on it and he ripped his last matress to shreds and put more fluff everywhere.....again today found some car cleaner and put that all over his bedroom wall and window sill

the other day he broke the old wooden fense (pretty crappy anyways) and took the dog for a walk without telling anyine...he quite often will just run away at shops home etc and not come when called

when he was younger at the old place he boke his bedroom windows,used to climb on the top of a 2m high cupoard and ended up breaking the back panel off,walked out at 2am and got in my car and rolled it into a pole

the list goes on of him doing things he actually knows he shouldnt but the thing is he is very emotional,sweet and loving...he loves to help and can be very good when he wants to although doesnt listen and help how you want sometimes...im just at my wits end we have tried time out taking toys smacking i even did PPP it only seems to work for a week or two then hes over it

has anyone had a similar child or know of a similar child and a good way to deal with it or what may be wrong......

he has even started at kindy and got sent to the principals office but has actually been really good then all the sudden he doesnt want to go and well run to the gate climb and open it and run back to the car and will just kep running back saying he want me and hes shy and i feel bad leaving his teachers to deal with him coz i know he will not listen for the rest of the day for them

sorry this is so long and thanx for any advice i really need the help
