Welcome to solo bunny life. She has definitely bonded to you. Some solo bunnies have social issues. Buns normally have a hierarchy they live by. My advice to those that have only 1 bun or are considering only getting one bun to really consider the best for your current or future companion. Buns do best in pairs. It’s just a fact.
I am VERY lucky to have a pair of males, brown medium hair lop and a Blue Eyed American White Dwarf. Literally a 1 in a million bun. We got them at the same time. They have bonded with each other. However, not before I bonded with Stewart, the Blued White.
So now he has a bunny bond and a human bond. If you can get this lucky, you will be a blessed bun mom or dad.
As for play time. Have you tried a neutral room in the house and just lay down on the floor, belly up and allow your bun free roam of the room. Your bun should start exploring around for a while. Once it knows the area is safe, he or she should start climbing or jumping all over you and binkies should abound!!!
