This tub was ok for the first 2-3 months, but by then I found that I had a lot of issues. Once my daughter could hold her head up, she did not want to lean back on the support mat for the infant side, but she could not sit up well enough for the toddler side. She slid around in it alot, and the plastic was so hard, that I feared she would whack her head when she looked from side to side. Once she could sit up, I tried it again, and she was too big. It was awkward, and uncomfortable for both of us. I would skip over this item, and go straight for a bath cushion.
