Yeah, for most parents, measuring age in months ends right around the one year mark.
I know plenty of parents who refer to their kid in months through year two, as you’re hitting milestones every month or two (vaccines, physical/psychological development, age limit for certain pharmaceuticals, etc) and “2 years” is such a big milestone for them all.
Also, kids who are premature make things extra complicated. I still refer to my son as “13-months adjusted” because if I said “16-months” people would wonder why he was so small.









Nor does it cut into the corporate revenues. They get paid for the ads either way. The odds of you clicking an ad (presumably) go down, though, so the click-through revenue the company would hypothetically get if you clicked on ads will be theoretically diminished assuming you believe the big tech companies aren’t lying about that data to their advertisers as well.
