I have used this bathtub for my now fourteen month old since she was born. It is a great convertible tub that makes giving my baby a bath very easy. I feel very comfortable and safe using this tub. The attachment that allows you to bathe a newborn is easy to use and clean. The baby stays on it very easily and has just enough give for the baby to lay on. Using the tub is easy too. The bump in the tub prevents my baby from sliding under the water. Versatility This bathtub is very versatile as I have used it for fourteen months so far and continue to do so for a few more months until my baby grows out of it. Ease of Use It's very easy to use. The sling attachment is easy to attach and remove. Safety I feel very safe using this bathtub with my baby. The bump has prevented many potential slips under the water. My baby is a mover and likes to stand in it and has not had any slips in the tub! Ease of Cleaning So easy! Just rinse with soap and water. It takes about 30 seconds.
