Bests & Worsts Reviews from Amazon

I thought this would be a great cup after reading the reviews however there is an inherent problem with mold. I will attach photos so you can see where the mold is building up. I have tried to keep this extra clean as always but the design of the cup is a breeding ground for mold. If you own one of these, I would pull back the ridges at the top and make sure you are not feeding your child mold.
