just wanted to say i'm having an issue with my DS. with bath time too.
he was fine until i tried to put him in the big bath tub. he screamed bloody murder.
we been given him a bath in the sink. so i figured since he can now sit up pretty well on his own. that i would try the big tub boy was that a mistake.. anyway we tried the sink again and he screamed. so what i did was distract him with toys and said Oh my what a big boy you are and he smiled at me and was happy once again. try lots of praises once she gets calmed down and plays with the toys. just keep trying different things you will find something that works.
