Those all sound like very lovely activities you can do to show her love as her Little! Caregiver/Little relationships are a special form of relationships, but they are not exempt from the best practices to maintain a regular healthy partnership.
When we were long distance with our Mommy, we each did our best to know about each other's lives and include each other in our day-to-day activities. We kept her involved and in the know of events occurring (such as our graduation, getting our first job, apartments, moves, etc). We made life decisions together, like suggestions on how to spend money, how to talk to interviewers. And we helped her picking places to stay throughout the few moves she had.
We did share quite a lot of our Littlespace through pictures, videos, audio recordings, artwork and sharing our ideas. We tried our best to bring up important discussions and put effort in talking about each other's interests, stressors, problems, achievements.
When we had problems (all healthy relationships grow stronger after properly addressing issues) we didn't shut down or hide in our regression — we always talked things through even if it was very uncomfortable to do so and even if it took months to achieve progress.
Be yourself, be comfortable being yourself, listen to them when they need to, don't be afraid to talk.
Best of luck with your Mommy!
