Hi K., I have a 12 and 9 year lod that are the same way. Granted mine are girls, but it sounds very familiar. They do not want to brush teeth, shower, comb hair, ect. And I always ask why they didn't do this or that and I get, "Because i wasn't told to!!!" I am hoping this ends sooner than later. My 12 year old use to be one of the most responsible 9-10 year olds and just over a summer she did a complete 360. Hopefully this helps a little. Good luck. My grandmother told me that I just need to have patience for the next few years.
