Dear Morgan,
Your mom is probably a little overwhelmed with everything she has to do at home. And by the time your sister and brother go to bed, she may not have much energy left to listen to anyone. But you deserve your mom's attention just as much as your younger siblings do. Find a time, maybe right after school or on the weekend, to let your mom know that you're feeling a little left out. Perhaps you can suggest an activity that the two of you can do together, like exercising or shopping, when someone else is available to take care of your siblings.
