My daughter is a huge fan of mirror time, so this provides her with that regularly. Also, when we were trying to get her to move from her bassinet in our room to her crib in her own room, this definitely helped her with the transition and start to see her own room as a good place to be. Before this toy, she wouldn't spend any time in her crib. In the mornings, this keeps her occupied with activity as I get ready to greet her and start our day. My daughter did hate tummy time, so we've never used it for that. One thing I do not like is the itty bitty straps to attach it to the crib railing. I had to get creative.
