Remember the rule: use fewer when you’re counting, and less when you’re measuring. You count how many kids you have, right? Should be fewer
Of course, some things can go either way, such as time. You can count hours, for example (Since I retired, I work far fewer hours than I used to.), but you can also measure the time using units such as hours (I spent less time at work today than I usually do.).
So pay attention to what you’re writing!
