Sippy cups. S I P P Y C U P S. I am not happy with my sippy cups. We use Gerber Sip and Smile 9 oz with hard spouts. I think they work well for awhile, but then they start to leak out of the sides. Those safety valves don't come out that often, but I'm sick of spilt milk all over the house.
So for all of you out there, what sippy cups do you like that DON'T LEAK?
