I'm having the same issue. I told dcd I'd try to keep dcg up, but immediately regretted saying that. I then said, I will see how she is and play it by ear. I may just leave her in the playpen with books.
She is just over 2 and I think she needs a nap her as much as I need the break. I don't believe in waking kids up, it's bad for their nervous system. So I think it's a phase or maybe she just needs a more strict bed time routine.
