Excitement or Nervous problem?

Sarika

Hi mum's, have any of you experienced your little ones shaking their whole body with excitement, the best way I can describe it, would be like a doggy when they meet you at the door. Our daughter is 3.5 years and is very well spoken, active and a happy kid for the most part baring the tantrums every so often.

I was wondering if this is something she will outgrow or is it something to be concerned about like from a nerve perspective. She does it for a few seconds a thought the day when ever she is excited.
