Query: Not good for big babies

My almost 5 month old is in the 100% for height and weight - so she is a big girl. I bought this tub because she is too big to fit in the bathroom sink. She cannot yet sit up on her on, so I needed something with support. I thought this would be perfect...but its not. She is too big for the Level 2 side - where she can sit on the little shelf and recline. And she can't totally sit up on her own in the tub side. This tub also slides all over the bathtub, so now I have to hang on to the baby and to the tub just to try to get her clean. Its gotten to the point where the baby will just scream bloody murder when she is on the shelf side. Last night was better because I tried to prop her up on the other side, but it didn't work that well either. If you have a small baby, I'm sure this tub is fine. But, with a larger sized baby, it does not work at all.
