What is morning nap like and at what time? Is it too long? Is she waking early in the mornings? Basically, what is her schedule like? From what little I know, 9 months is too young to be only having one nap. And, when they do go to one, you want to ensure they keep the afternoon one. If you can, send us her routine and maybe we figure this out. It 's so frustrating isn't it...you just fixed the night problems and now you have daytime issues. They're lucky they are so cute!
