@vicorva I'm thinking of moving us to a house long-term (should the stars align) to give Tater some space of his own as he grows, and the stairs are what give me pause: All my neurodivergent friends have problems with leaving things on a different floor and then having to go up and down stairs to fetch them, and I don't expect either the recall or the stairs to get easier with age! xD It may, however, advantage Tater in keeping parental incursions up the stairs to a minimum.
@Satsuma @vicorva It's good aerobics for sure, not so much for older folks' knee joints! I have fond pipe dreams of an old-timey mechanical elevator or a wildly spiraling ramp...
