Whooo hooo our little Nightowl is outgrowing her crib, now there's progress if I ever saw it 😁
All jokes aside, that's a tough decision to make! Our 1970s acoustic piano had a mute pedal that you could lock in place, but I hated the sound because it was so muffled. I have no idea if modern pianos have a more sophisticated system than just a layer of felt.
Our 1990s Clavinova of course can be adjusted to any level and continues to sound gorgeous. It never needs tuning. And when we moved to this house, it didn't require specialized movers. Also, a digital piano is sampled from high-end grand pianos, whereas with an acoustic you may need to spend some time trying to find one with a good sound. Some sound dreadful!
I think that a really good digital piano might be the best of both worlds, but the two piano sections in this forum might be able to help you make a more informed decision. 😊
Edit: whoops cross posted!
