Does anyone else’s baby shake when excited? It’s almost like she doesn’t know how to process the emotion and is overwhelmed by what she is feeling..she puts her hands straight out, clenches her fists, makes a funny “open mouth” face, and her whole little body shakes. I’ve googled it and it SAYS that it’s could just be her little neurological systems still forming, and it seems fairly common. The pediatrician didn’t seem concerned. But she’s 8, going on 9 months now and still does it and I’m really beginning to worry that it could be early signs of autism or a neurological issue. She is my second baby, and I never remember my older daughter doing this..
