Hi M.,
I think it's a bit young to drop the morning nap, it usually happens closer to 12 months. I would start putting her to bed earlier at night...no later than 6:30, possibly earlier depending on when she woke from her second nap. Ideally you want closer to 12 hours at night.
I appreciate how its necessary to listen to our children's cues, but sleep is so important and so good for them. She's probably resisting sleeping because she wants to spend time with you which is understandable. But, you are her mother and you know what's best and if you feel she should still be taking that morning nap, I would work on it until it comes back.
Check out Healthy Sleep Habits, Happy Child by Dr. Marc Weissbluth. It's not just about sleep training, but it helps with sleep problems (like reintroducing the nap) and offers guidelines as to at what ages children drop naps.
Hope this helps and good luck!!!
