Query: Made for kids? Don't drop it!

I purchased four of these for my children (ages 2-4). After using them for a few months we have had a variety of issues. The plastic on the bottom of all of the cups has cracked. One of the straws ripped apart. Also, the plastic hinge broke off. After contacting Thermos they said that there is a five year warranty on the cups ONLY if they haven't been dropped. These are made for kids right?
