My daughter, now 19 mos. old, did the same thing. It's very hard (for us) to give up that morning nap. I would just start putting her down earlier for her afternoon nap. She'll prob. sleep for a long time. I will warn you that if she's like my daughter, she'll start refusing naps all together on certain days starting around 16 mos. When that happens it's hard to get anything done. Good luck!!
