However, this information could be unmentioned, or there could be cultural values of the time and place that are at work. Also of note are the facts that the character's family is obviously poor, and that children of his age are generally self-centered. The view that the character is neglectful of himself and his duties as well as neglectful of his family, is one that I had previously taken. He does not take off his clothes when going to bed. He also puts off doing the dishes, which is his responsibility.
More information is needed to make an informed judgement here.
Maybe his mother is babysitting small children who aren't related to him, as it is mentioned that everyone in the family had to work. There might be no new diapers to put on, or he might not even know how to change them. Although I believe that the character exhibits addictive behaviors, it is not certain whether this is positive or negative. The grocer knows exactly what the character wants without having to ask, indicating repetition of habit. The wino apparently knows where to get the money for his habit without working for it.
