Night Terrors

My 4 yo gets night terrors when he doesn't nap during the day. He doesn't nap as often anymore (even when I try to get him to), so the night terrors are happening almost every night. We try to break the sleep cycle and wake him up right before the night terror occurs, but it doesn't always work. Anyone else have a kid who has night terrors almost every night? It's been happening for at least a year, just not so often back then because he would nap more often. The whole thing is just frustrating. When he stops napping for good, is this gonna be an ongoing thing??
