LO is 19 months. He's been on the Zoli straw cup since he was 11.5 months and it has been easy for everyone. Daycare uses it, and I usually bring the cups with us when we go on trips, outings, or to restaurants. While it is bulky, it works just fine and a (lazy) mom needs a break sometimes....

However, just now I read an article that we should really have cut him from the sippy starting 12-15 months and some studies suggests sippies may affect speech (!!!) What? OK I've been lazy, and I guess I will do it now. I am just not crazy about all the spills that will happen...

Now I wonder, have you switched your toddler to an open cup, and when / how did you do it? Do you just give them a cup of water at mealtime and just let them spill allover themselves?
