We didn't have one for 5 years and last year did a bathroom reno and put one in- bliss! DD often has a shower with one of us in the morning and then a bath by herself or with DH at night. When she was a bub (before we had the bath) i would sit on the floor of the shower and hold her, when she got bigger she would sit in the bumbo, and now she sits on the floor. we still have a few bath toys in our shower for her to play with.
