I can understand her behavior in this chapter but I find it irresponsible of her to refuse to have maids/servants help her. It's one thing if she's by herself but she has a child. If she's sleeping most of the time and only getting up to make food, she's leaving her child neglected on the side. Young kids can seriously get themselves hurt when there's no supervision and I've already read horror stories where children have died because of it. And this is besides the fact that we know the kid is malnourished due to her limited cooking abilities and what she has in her kitchen. This is just sad all around.
Also, now that the ML is back in the picture, she should tell him he's the biological father. He has the right to know. Not only will it give the ML more motivation to help care for her son but her son will finally get to welcome another family member into his circle. He needs that because it seems that he's pretty much isolated with only his mother and that's not healthy.
