Query: VERY disappointing

When our 5 wk old is in the sling, he slides down and the middle snap-thing at the bottom of the tub digs into his bac, also leaving bruises. Very, very poor design. Also, it doesn't even COME CLOSE to fittingin our single kitchen sink. We refuse to use it anymore. We are gong out to ge the First Years Sure Comfort Deluxe Tub this weekend. It got 4.5 stars out of 5 on amazon and two couples we know swear b it. We should've talked to them before we put this on our registry!
