Our other kids that are now grown have pretty much always done their laundry since they were like 13 years old. This son is 17 and probably has only done his own laundry, all on his own, like 10 times in his life. He has a ton of clothes, probably doesn't wear most of them, but I think he tries on a lot of different clothes and if he decides not to wear this shirt or those pants, he just throws them on the floor and they likely just sit there for 2-5 weeks before he starts doing laundry again which usually ends up with him begging for us to help him finish it.
We've already tried explaining that laundry really isn't that hard to do, just throw it in the washer, if there's stains spray some stain cleaner on that part, etc. That it really doesn't take that much time to do it, since most the time it takes to do laundry is the time in which you don't need to do anything since it's in the washer/dryer.
Obviously he has other cleaning issues. I just don't understand how he can care so much about his appearance when he goes to school, but be so dirty in his room with more clothes as the floor instead of carpet. Does he have too many clothes? Should we give/sell a lot of his clothes, because maybe it's just too many choices on what to wear, in that it makes it harder for him to decide? With less clothes he would need to do laundry more, which could mean that maybe he could start forming a habit of actually taking care of his clothes on a regular basis? What can we do, really?
