We have one, she fit in it until about 5 months (she's very tall, always was), then i switched her to a baby bath. There is NO WAY a toddler would fit in it, she couldn't have even sat down in it at about 9months old and you'd be unable to reach to actually wash them.

We never bought the stand and bathed her on the floor which was fine. I loved it as it saved water and was a space saver too. I wouldn't recommend using a normal bucket as they have a flat bottom (the tummy tub bottom is rounded) and have corners and sharp bits of flash (where the plastic was moulded) which could hurt bubs delicate skin.

If you're going to have more than one baby they're worth their money. I'll put a pic up in the gallery...here
