Hi Bena,
Actually different kids develop in different areas and at different paces. Some are better at their motor skills, some more auditory, some may be great at verbal capabilities. But since your little one is already speaking single words, my opinion is that she is perfectly fine! At least I didn't utter a single word till 28 months. Like Brenda said, she may be quietly absorbing everything.
Clarence's vocabulary is largely limited to single words as well, it is only rare rare occasions that he strings 2 words together like "more bananas". He understands simple instructions in sentences, such as "plse put this in the dustbin", but is just non-verbal. But we are not concerned. Just let him grow at his own pace.
However, if you are still concerned and wish to help your little one along at developing language skills, maybe you can try the following suggestions:
1) Sing or talk to your little one at every opportunity. Go slow with your sentences and face your child, such that he/she can see your lips and follow your intonations.
2) Don't always tell your child what to do. ASK open ended questions, like would you like some bananas? these yellow bananas are yummy! OR ask questions when you tell stories. Look at him/her expectantly when you ask your questions and pause to wait for a response. Even a babbled response is good. This encourages the child to speak.
In short, don't worry too much yah? Sometimes your little one may just be shy, ie can talk but is shy to do so. So well, just give lots of encouragement along the way and let him/her develop at his/her own pace. You will have a real talker soon!
To all moms who are expecting or have delivered:
A HUGE CONGRATULATIONS!!!!
