Query: less than impressed!

This is probably the hardest to use baby tub, it is bulky and hard to use the shower with the newborn. the temp messure is barely legiable, and my baby hated it. My newborn kept sliding down and she barely fit length wise. She is 21inches long. I just used it for the first time before she went to bed and i am going to take it back asap. I think i will stick with the older style tubs.
