sippy cups

Meredith • Mother to my rainbow baby girl 10/21/16 and 1 on the way due 1/4/19 🌈🌈
I need recommendations for a good sippy cup for my 8 monther so she can start drinking water (constipation). We have tried tommy tippee and also having her drink water in her regular bottle but she is not excited about it. Suggestions?
