My little girl saw the advert for this and desperately wanted it - she got it for her 4th birthday and her delight soon turned to bitter disappointment I am afraid. Firstly, it's not actually very easy to make the doll do what it is supposed to do - ie walk and splash. When you do so you feel like you are twisting the limbs off and it doesn't actually splash or walk very well. The main issue though is durability, for the price this is shockingly bad. Our doll was used twice, completely following the instructions, and then dolly "died". I'm afraid batteries + water is probably not a great idea. The only good thing about this doll is that it comes with cute accessories, but I don't think this is up to the standard of normal Baby Born items, and I think it is one to be avoided - if your child is enchanted by the idea of this, try and talk them into something else, as if it breaks after very little careful use as ours did they will probably feel very let down, as we did. Not recommended.
