I think that's how you page someone, right?
I was just reading your Say Anything response and I wanted to comiserate with you! My son has mild gross motor delays as well. We are in PT once a month. He actually started PT when he was about 3 months for torticollis. He was about to "graduate" and be discharged for the tort, when our PT suggested that he be evaluated for gross motor delays. I suspect that he has low muscle tone as well, but the PT (nor our pedi) has ever mentioned it.
Anyways, I can totally identify with being paranoid about their prognosis in the long run...especially with the help of evil Dr. Google. And my DH is the opposite: a combination of being blindly optimistic and/or in denial.
We went to a Mommy and Me type class over the weekend and it was hard to see other tots (who were obviously younger than my little guy) running circles around him. I know, in the grand scheme of things, he is very healthy and happy. I try so hard not to compare...but it can be tough every now and then.
