I’ve always taken their lead with nap-times. I think they all gave them up between 2 and 4. I have an almost 3yo who naps most days (but skips a day here and there). Basically, when she’s tired and cranky she lays down with me for a bit. Other days, she’s too busy playing and in a cheerful mood, so I don’t have her take one.
I think if you need the nap time, I’d be working on quiet time…some families have a “books on bed” time. My preschooler has an assortment of books that don’t require reading…I-spy, interactive pop-up books, books with lots of pics, etc. I’m sure this would work in your office if you put a blanket or chair in there for her to sit on.
