Sammiejane thanks for that opinion, my mother in law offered to buy us one as a gift but when we went to the shop, the saleslady was a bit negative and put us off at the time for a bit, although she wasn't speaking from experience, she just said that none of her customers had bought one so she hadn't had any feedback. I am still keen when thinking of the idea - after your positive experience I might tell my mother in law to go ahead as she was quite keen in the first place! Good point about occasional baths with dad to get used to more water.

(sorry for the thread hijack - it's been interesting reading though!)
