Dock-A-Tot Use

Ashley • Welcomed our first child, a baby girl, into the world on 8/5/17! ❤️ Took 5+ years to get our little baby! Now pregnant again with baby #2, feeling over the moon! 👶🏼👶🏼
What exactly is the dock-a-tot used for? I have two bassinets and a crib. Not getting a playyard because I think they are ugly and hubby and I are too tall for all of them (hubs is 6'8"). Would a dock-a-tot be worth the money and for what? LOL
