Not important, but I still want to know...

what's considered "gear" vs specifically categorized baby stuff?

BabyList has an option for gear as well as Travel/ Transportation, Books & Toys and Bath time etc. Initially I had two items under Gear: rock & play and play gym that the baby lays under. I reacted or iced the play gym under Books & Toys.

What is the Rock & Play considered? What other items could I add to the Gear?
