Hi and welcome!
there are some charts and lists around on the web,
like these:
http://childparenting.about.com/od/childdevelopment/Child_Development.htmhttp://www.nncc.org/Child.Dev/ages.stages.2y.htmlKeep in mind, these are ranges of "normal" development. And often used as tools to make sure kids are not behind in any area. (there are several threads on this topic in the archives of this board that you can search for)
I found it helpful to be able to observe my son with other kids and that told me a lot. If you have the opportunity to do this it can be a real eye opener.
When dsnow5 was 18 months we were in a co-op with 3 other families. age ranges were 18 months to 23 months. Verbally, my ds was where the older kids were at.
when he was two years old he went to a small preschool with 2 to 5 year olds. (he was the youngest) activities were mixed-age. he did well there.
we moved and he went to a larger preschool with classrooms grouped by age. that's when it clicked for me that he was more advanced than the other kids. He had been able to speak in sentences and have conversations since two and the others 2s and 2.5s in his class could not. for this and a variety of other reasons he was borderline miserable . the school did not want to put him in the 3 year old class because he was not all the way potty learned yet. Even though the activities, language skills, etc. were more on his level. they couldn't get past his chrono age. we left the school.
this does not answer your question but maybe some food for thought?
