time?
Like "today, yesterday, tomorrow"
Dylan's always asking if "today is a nanny day" at the end of a weekend day. It's like he doesn't conceptualize tomorrow very well.
Likewise anything that happened in the past was "yesterday"
But on a lighter note I think I'm gonna petition Webster's to include "yesternight" in the dictionary.
I think it's a cool word.
I don't dare teach them the correct word because I'm gonna be sad when I don't hear "yesternight" come out of them any more.
Re: What age do they learn....
My daughter is the same way! Anything that happened in the past is either "yesterday", "last year" or, my personal favorite, "when I was little."
She does better with the actual days of the week than with today, tomorrow, yesterday. Not sure when that kicks in.
