Hello, I have had so much great input in the past from this forum so I thought I'd try again. The photo is of the boxes I built for my vegetables but I'm left with a pretty large open space that I'd like to devote to a kid friendly area. I'd like for both me and my 2.5 yr old daughter to have reasons to come to this side of the yard! The problem is it's currently rock and a fairly large size rock at that, it's not even pleasant to walk on, let alone for my daughter to play. I'm ruling out lawn for various reasons, I'd love ideas on how to turn the remaining space into something fun and forgiving for my daughter.

Thanks in advance!
