The more important thing to look out for at this age is, is she trying to communicate in other ways? Using signs maybe? Is she babbling?
I dragged my kid to a speech/ language pathologist at 14 months... she had around 5 words, but I was more concerned that she wasn't babbling enough. I didn't know what "normal" babbling was supposed to sound like in terms of range and frequency. I think they thought I was nuts. Well at 18 months, she had 50 words, around 2, she was talking in sentences, and now at 30 months she's talking in paragraphs and won't shut up.
Your LO will most probably be absolutely fine, they develop so differently. But you're right to be on the look out just in case.
