Good for when Mom is driving you to school, practice, games, friends' houses - basically everywhere! She can turn it on and enjoy you listening quietly in your seat.
Or maybe you'll get Mom a shirt that already says "You're in Trouble" to save her from having to say it one more time.
Or you could get Mom songs that she can enjoy when she's on her own.
Or you could get her a book that might offer some tips on how to talk to your teacher (though you NEVER get in trouble at school)
