Any advice???

We could use some advice about naps. Mattie has always been an awful sleeper weather it be too short of a nap, multiple night awakenings, early rising, and now NO NAPS! She has not been having any night awakenings, but wakes up anywhere from 5am to 615(on a good day!). For the past week she wont take a nap. She just plays and talks to herself in her toddler bed. She does not get out, but is beginning to run and jump in her bed. I have taken her lovey and blanket/pillow, I have given her timeout, I have rocked her, I have sung to her, I've read her stories, and I've even sat in her room to make her still. This is hard because a 3 month old needs attention too! He is usually sleeping during this, but I have had to leave Mattie due to his screaming from across the room. We are putting her to bed earlier when there is no nap. Mattie is 22months and those of you that know her really well knows that her mind won't stop. She is talking a lot and just wants to play! I am happy to have such a creative and intelligent child, but the afternoon grumpiness from no nap is awful! Any advice would be great. Leave me a note in the comment area or email me!

Thanks!
Elijah is doing great! We have learned how to keep his eczema under control with less baths, dove bar soap, lots of eucerine cream, occasional steroid cream, and we think the new formula is helping. He still has lots of spitting up and painful reflux but other than that very happy and laid back! So thankful for that!!! We go for his 4month check up and shots in Feb. so look for weight and length updates.
