Fear of traveling?

How did you get over your fear of traveling, or, more specifically, flying, and leaving your kids at home? I want to take my husband on a trip for his 30th birthday in the spring. My daughter will be 2 and my son 6 months. I’m not nervous to leave them for a couple of nights overnight but I’m terrified for both my husband and I to fly out of state. Like...what if something happens to us 😭 we’ve flown plenty of times in the past but not since we had kids. How can I overcome this anxiety? I don’t want to be afraid to live my life but this makes me nervous!!!
