G.,
It sounds to me like you have answered all your questions already on your own! Your mommy-intuition has done that for you. It could be HER "normal," (whatever that is) a speech phase, and also anxiety about the up coming new addition. I think yall shouldn't worry or stress about it, as you said you weren't, and just let it work itself out, her speaking skills are still developing and will be for years to come. Yall are doing the right thing by just encouraging her sometimes while speaking (not too often as to make her self-conscious--she is only 2). But I don't know about stopping her while she's talking...that might make it worse. I think you should DEFINETELY NOT even think about a speech therapist or evaluation--I'll bet your pediatrician would say thing same thing, especially is this is the only "symptom." My son is almost 3 (birthday in Jan.) and a few months ago he started the same type of stuttering while starting his sentences, and just repeating himself often like he was having a hard time getting his sentence just right like he wanted to say it. He is, just as you described your daughter, an early talker, speaks proficiently and talks a lot, and holds long intelligent conversations too. We just let him take his time and say what he wanted to say it, how he wanted to say it. If we bring attention to it, it makes it worse I think and he starts to get more nervous or something and it interupts his thinking to where sometimes he wouldn't want to say it anymore and the thought passed already. We just listen, simply listen and make his words and input, and observations and comments important. So cut her some slack and let her work through any speech "issues" herself. She can't be so "perfect" in every way...she's precious the way she is! That is what we've done with our son. Everyone always comments on how "smart" and advanced he is for his age, etc....blah, blah, blah. Sure it all makes us feel good as parents, pats on our back...but, (because we talk with him a lot and not just "baby" talk, we explain things to him, include him in daily conversations, etc.) however, we give the credit to God...not ourselves. Let your little girl speak and communicate the best she can and she should improve on her own with yall's encouragement and soft guidance, don't allow anyone (docs/therapists, yourselves) to already start labeling her with some sort of "special" need, disability, speech impediment, etc. Just continue to help her with ABC's, words, singing, speaking, expressing herself, etc. And don't worry...she'll pick that up from you and start to be way too self-conscious! Happy parenting--it's a privilege! :)
