Will naps just naturally get longer?

Or is there something I should be doing to help lengthen them? Just wondering if it's simply okay to just let her 30-45 minute naps be what they are until they naturally get longer? Or if I SHOULD be doing something to help her learn how to connect sleep cycles? Are y'all just letting them be or working to lengthen?

Edit to add: LO is 5 months in a few days so I hear it'll likely happen soon, but just curious!
