When your child is too big to bathe in the sink and too small to bathe in the tub this is the transition stopover that will delight you both. You use this within the tub, but it gives baby a much more enclosed and safe feeling. There is also a texture on the bottom which reduces the chances of slipping. There is a temperature monitor that indicates when the water is getting to hot which parent really appreciated. The tub is nicely packaged so that you fully understand what you are getting and what you can expect from it.
