Carly is not quite there yet. But she does roll, sit up, roll, turn, scoot, roll , backwards crawl and roll some more.
I think that if anything will get her crawling it will be her intense desire to get to Lola. She is always reaching for her, which sends Lola running. She doesn't like to be bothered - even by adorable little T-Tinies.
Don't worry. She's not as frustrated as she looks.
