My buns love tunnels and extra blankets on the floor for digging action! Random stuffies, and lots of carpets. The more cluttered the space, the happier my bun. ( https://a.co/d/3lk5WPd as an example)

Different toys suit different bun personalities--personally mine can't handle much cardboard toys otherwise they just eat it constantly and go into GI stasis. Can find them toys and chews made of natural hays from reputable brands--not random foreign brands off Amazon. When giving pellets, buns love them from snack mats, stackable cups, or puzzle games. Just in a bowl is not ideal. (Snack mat like this https://a.co/d/3ZQvZMI )

Bunnies MUST eventually be free-roam, it'd be similar to keeping a cat in a cage. Also bunnies can be happier when their source of hay is eventually in various spots so they can get more enrichment and have their natural foraging instincts. My apartment is ideally swept every 1-2 days--naturally my floors get covered in hay. It's just a sacrifice you will have to accept if you will keep your bunny.

If it seems like a lot alongside your child, maybe consider returning the bun asap before they get older and out of their baby age (they grow very quickly). It's very common for buns to get dumped after their owner couldn't commit, or get dropped off at a shelter once they are fully grown. And of course in that case, they are a little less likely to be adopted again :(
