Getting my daughter used to her new bath seat?

My daughter usually had her bath in the 'baby bath' up until last week as we got her one of the rings that they sit in and it suctions on the bath so you dont have to hold them, every time she has gone in it she has cried and screamed until shes taken out, she goes rigid and makes it difficult for us to sit her in it. i know its a bigger bath and probably scary to her as she always loved her daily baths in the other one, but i dont know how to get h er used to it this way and enjoy herself again. shes got bath toys but at the moment cries to much to even notice theyre there. can anyone give me any tips? i was thinking of getting in with her next time to see if that helps but i doubt very much it will. thanks.
