Justine,
I had a baby bath for my DD only ever used it once. I got this plastic bath tray that DD laid on which was fantastic. It takes bubs up to about 10 or 12 kgs. It elevates them in adult bath so not so hard on the back. Thought this was great and bub loved it. I also have a buggered arm so am kinda one handed so this made it much easier and safer for DD. Would not ever use a baby bath again.
