G.B.
I made the kids stay with straw tippy cups until they were...well, 2 years ago I guess is when I gave them away. The kids are 6 and 9.
I didn't like cleaning up spills so I made them use big kids straw screw on lid cups. I don't know why you want to make a 3 year old use a cup with no straw or lid....messes.....
