We are starting DD on her sippy cup in 2 wks when we start her on rice cereal and pureed foods!! (exciting!). We just bought the Nuby one as i've heard lots of babies like those one's and it was on special. It has a soft spout.
I'm going to give DD EBM in it rather than water at this stage. Not sure if she'll take it or not though but it's worth a try....
