Yes - Jen your problem is different but for both of you, a part of the issue could be developmental - going to sit, stand, crawl, solids, etc, etc. They all effect sleep and you don't what it is until it is over.
Jen I would also look at your A time, it maybe time to increase it. She may not be tired enough to sleep yet and is happy to sit and play. For us at this age, 2.25-2.5 was the magic no.
Hope that helps.
