Removing the details may not be a good idea. The word is that Airbnb "mines" the amenities section for these details and the algorithm uses that data to match guests in search results. This could mean not only would Airbnb consider your listing "incomplete" without those details, you could be overlooked in search results depending on the guest searching. This is probably why you can't remove details once added (you can change the details but not remove), as Airbnb wants you to have those there. Also, "crib" is a search filter, but that has some controversy, as I don't consider a pack n play as a crib, but others do.
I suggest to my clients they take a photo of all the child friendly amenities in one photo and add to the listing:
High Chair
Pack & Play (show it setup)
Changing Table
Baby Bath
Baby Monitor
Child dinnerware (sitting on high chair tray)
Add a caption that your provide kid-friendly amenities always available in the listing, or available upon request - whichever you want to do.
Guests are not going to consider your listing "cluttered" if you are not showing all these amenities in deployed in other photos.
