Query: Great for sitting up

I bought this tub after my daughter was four months old. We had the 4 in 1 tub for her as a newborn and I hated it. It was so uncomfortable for her. I only used the sitting part of the tub for her, but it has been great. She learned how to sit with the help of this tub.
