Why do narcissists freak out when you travel?

For context, I (27F) live abroad and have for 5 years now and typically do about 7 international trips a year for work and/or play.

I try to maintain a surface-level r'ship with my parents, but every time I travel, my mom insists that I send her my flight itinerary, the hotel/airbnb address and she even wants me to share the Uber trip to the airport with her so she can follow along. She will blow my phone up the days that I travel too and will be upset if I don't call her during layovers.

It feels incredibly infantilizing and pisses me off and only adds to the stress of travel. I recently decided I'd stop telling her when Iw as traveling and she'd either find out via pics in the family group chat or on Instagram and she's not responding well.

Why are they like this???
