I'm sorry they made you feel like crap. It's good that CC are looking out for your DD,but they're not speech pathologists are they? (And apparently I don't know how to read books either)
It does sound like your daughter is very happy and healthy - obviously you're doing very well. If you're concerned about her speech, then seeing a speechie is not a bad idea. Maybe they can help you out. And maybe they can offer some reassurance.
