I have been giving my LO (4 months) a bath in a normal baby bath but it is proving much too small. Unfortunately we don't have a bath in our house or a sink big enough for him. I was considering getting the flexibath but was also wondering if anyone knows if bath seats fit with this and if so which ones? He really likes to kick around a lot and I find it quite difficult crouching down on the floor while he is flailing about! Does anyone have any recommendations? Thanks so much.
