Child Support Question.

When I was a kid my parents got a Divorce I was me and my two siblings. My dad paid child support to my mom. My mom always called it her check. As we were growing up we didn't get new clothes shoes just basic needs. We never got what we wanted. Instead mom would spend the money on rental furniture and waste the money. We were going to school with holes in our clothes, clothes to small or way to big, and never had actual school supplies. My point is, is that the child support check that mom received was it supposed to be saved and spent on our needs or was it just suppose to go in her pocket??? Now as an adult I kinda feel robbed of a Childhood. What are your thoughts and opinions?
