Hi S., I have an almost 2yr old and she does the same thing. Some kids are just like that to where they don't need to take naps. Taking naps are for the baby's well being. As long as she isn't cranky or throwing temper tantrums or anything like that, then the sleep that she is getting during the night is plenty for her! Now I know what you mean about that being the time to get things done. I call it my down time now since she is off and on about sleeping. I still put her in her crib so I can get my stuff done and get back my sanity since I also have a 4month old to take care of and is on his own schedule! She just plays and talks to herself while she is in there. Maybe she will take a catnap for about 15min.
This is my advice, but don't worry about whether or not she is ok, she is perfectly fine if she isn't showing any problems!
