Quoting BakingBean2:" That's good! That's what I was worried about, she doesn't really have to use her words because me and ... [snip!] ... the older she gets. So lately I've been trying to get her to say more words, but if she is on target I won't push it too much! "
A lot of kids are speech delayed solely because they don't NEED to talk because someone else always does it for them. My little sister didn't talk until she was almost 3 because all the older kids translated for her. DS doesn't talk because he doesn't want to and because we generally know what he wants, so he's never had to. I didn't even know he was speech delayed until his pedi asked how many words he used and I said none and he got all concerned, which upset me a lot lol.
I wouldn't push her to talk more but I would definitely encourage what she is saying. But I think she's right on track
