K, I doubt they will expect you to outfit him in designer gear and buy him a new Sealy Posturepedic. Seriously - he needs something to sleep on, and something to cover him decently. None of it has to be new, or in vast quantity. Just sufficient.
I've been at the stage where I needed to keep my boys clothed, but they were destroying clothes as fast as I bought them. Notably, school uniforms, which were not made of serviceable fabric. Neither of the boys was choosing to be destructive, but the school playground has a large rocky outcrop that both boys used to love to clamber over. They would come home having ruined and worn through the knees of their brand new school trousers. So I patched the pants with vinyl. Or denim. Then I sourced denim jeans in the same colour as the school trousers, and sent them every day i those. If the school complained, I told them why and promised I would let them wear good school pants on excursions, as long as they promised to keep my boys from ruining those clothes while under their supervision.
difficult child 3 also chewed his clothes and would 'worry' at any small hole until it was huge - kind of like Michael Jackson in one of his South American videos, when his shirt seemed to get bigger and bigger rips in it, through the video clip. Any shirt that had even a microscopic hole in the morning, would be rags by lunchtime. Half the time he actually chewed a tiny hole in the neckline at recess, and had a huge hole by lunchtime.
So I began buying old, second-hand clothes and found an unexpected dividend - the boys preferred the feel of old clothes, because they were softer.
I found I could outfit both boys at op-shops for the price of a single pair of jeans from Target. If the op-shop clothes are clean, neat, not looking worn or frayed, then there should be no problem. Even as a newborn, difficult child 3 went into an entire op-shop wardrobe of clothes.
