Read, watch Netflix on my phone, puzzles like or games on my phone. Walks outside. Im usually nap trapped or running around doing jobs
Have something to look forward to. Like bed time is at 7. Wine time at 8 and read or movie.
If you enjoy reading, do that!
Cook a new recipe, bake, blend, read a book of your choice out loud so baby hears your voice, exercise, stretch, yoga, meditate.
