Explanation:
Fewer is used for things that can be counted such as, kids, chairs, balloons, etc...
Less is used for singular mass nouns
Here’s a tip: A good way to test that a noun is truly uncountable is to try making a plural out of it.
<u>Example:</u> I told Cookie Monster to drink fewer/less <em><u>milks</u></em> or he would get sick?
