I am a speech pathologist and it sounds like what you have described are errors she may grow out of; however, I will say that I would take her in for a screening just to be safe. The screening is a short (usually around 30 minutes) sort of pre-evaluation to see if she even qualifies for a full-fledged evaluation. I hope everything works out great for her!
First, based on my current understanding of language (which is NOT professional, it's just as a Mom), it sounds like your child's language is age-appropriate. And I agree that an assessment is a great idea, just to be sure!
I have 5 year old twins--one with excellent (over the top) pronunciation skills and one who has had difficulty forming words from an early age (talk about fraternal!!!). We did a speech assessment at 3 years old (very early on the spectrum--based on my need to understand her better--the pediatrician was not supportive!) and worked with a speech and language pathologist for about a year.
The great thing about our experience was that it was fun, useful, and confidence-building. Our therapist allowed me to bring our language-loving twin now and then. We also made sure that my husband, my mother, and I all went interchangeably so that we'd all get exposed to what our daughter was learning so we could reinforce learning consistently. We also were very committed to doing our "homework" and the girls actually asked for the "games" nearly daily.
Then, we sort of outgrew our therapist...and did nothing for nine months. Just recently we found (via acquaintances of ours) another great pathologist, so we're getting back on the horse again.
For us, speech therapy builds confidence for our daughter, is fun for the family, and reduces my stress level (not understanding words and worrying) and increases verbal intelligibility for others listening to my daughter.
I guess my last words are: it's sort of an "extracurricular" activity for us (versus something we don't look forward to).
Wishing you lots of language fun!
