Query: Very Disappointing!!!

Everyone knows how awkward it is to bathe an infant, so the sling on this tub is what had me sold. Boy was I wrong! My son screamed in this tub. The sling got very cold once it was wet(not to mention there was a "bump" in the middle of the tub that dug into my son's back). It took us using it only once to determine that this tub will not work out...what a waste of money! I have learned that the items with all the bells and whistles are usually not worth the money spent. We are now using a very basic sponge-type bather that sits in the tub and stays very warm. Now I get nothing but sweet smiles during bath time.
