They are currently free roam in just one of my rooms. But new parents are welcome to everything I have for them.
Items they have:
2 leak proof water bottles
Oxbow vitamin c tabs
Those multicolored foldable pen cage thingies (4 of them)
If you have any difficulty placing them, I encourage you to write Talishan, who I believe is in Atlanta and perhaps can offer some advice (or has more ideas).
