Hi 1 year old ds currently uses a free flow sippy cup with handles for all of his drinks (he doesn’t like valves and prefers free flow.) The only problem is because it’s free flow it spills easily and it’s difficult to the out. I’m looking to upgrade him to a bigger toddler cup for home and to take out with us. I’m overwhlemed by all of the the cups with straws, sports bottles, fancy curved shapes and added fancy touches; I have absolutely no idea what to get. What do you find works for this age? Thanks.
