So many movies mentioned and you did ask about kids so this might not count.
Mad Max, Mel Gibsons wife and baby are run over by Toecutter and his gang.

Hunger games..well teenagers at least

Frankly, I don't give a damn if some kid dies. What gets me is when a pet dies like the dog in Jurassic Park II. The Independence Day filmmakers were smarter and had the dog make it into the storage room in the nick of time.

The Blob 1988
Alien Vs Predator: Requiem.
Jaws
IT
Salems Lot
Final Destination 2
Maximum Overdrive
