Rolling over. Now what?

My baby boy is rolling from back to belly. He did it once on Tuesday and I thought it was a fluke but he did it again today 4 times.

He's currently sleeping in a bassinet at our bedside, but they say to discontinue once baby can roll.

What do I do now? I'm not comfortable with him going to the nursery yet, and the crib won't fit in our bedroom. We knew this was coming soon as he's getting too tall for the bassinet as well.

Thanks for any suggestions 😊
