After baby starts moving more and wanting to splash.. this tub is worthless. The bump in the middle that is suppose to hold baby in seeted position is worthless, they slide them selves right over it so it is then digging in their little backs. Also, it's not very slip resitant after your done with the hammock portion (wich starts to smell bad even rung & hung to dry) They grow so fast, don't waste you money on this tub.. I'm currently looking for another for my almost 6moth old son... Any ideas would be appreciated!
