why do you have four kids if you are a single mother God i hate it everytime I see people like this People shouldn't have kids just because they have parts to make it Now you are just going to expect the kids to spend there entire childhood helping in chores. one of them is baby, one of them is special needs so obviously the other two would not only have to take care of chores but will also have to become part time parents at young age without there consent to of your two other kids because you wanted so many kids

Why do parents never see this as a problem

i can literally see your children cutting off all contact with you as soon as they run away from you when they turn 18
