Divorce with children

I'm watching Teen Mom 2 and it breaks my heart to watch these kids get shuffled back and forth between their parents' houses. My parents divorced when I was 7 and it was so hard for me every time I had to leave either one of them (they lived in different states so it was long breaks). I know things happen and that sometimes divorce is the best answer but I also see people splitting up over things that should be worked on and I just wish they would think of the kids. I know everyone has their reasons but it's still heartbreaking.
