I hate that the go to is "Wait and see..." When I knew something was up with Charlie (she couldn't support her head at six months adjusted and hardly moved on her own), the general consensus was "Wait and see."
I would hate to see where'd she would be had we waited. Instead, I found a doctor who agreed with me that Early Intervention couldn't hurt. Grrr, it aggravates me that they told you to "wait and see"
I fully support going with one's gut. A parent's instinct is generally correct.
