Thanks ladies! SLP and ped agree there is no autism or anything similar going on. Her speech eval showed cognitively she is great and on track, maybe advanced. SLP said as far as they can tell and based off the eval her only delay is expressive, everything has checked out fine.

I'll wait and see how DD7's eval goes. If it shows high IQ then when DD3 reaches school age I'll address getting an eval then. I don't want to get inaccurate results or spend that kind of money if 3 is a too young and won't make any difference right now.
