"Well, I'm sure you're right. I really try to do that." is the reply.
BUT...what I really want to say is...
"So, you think I should treat my child with cerebral palsy like a normal child, because your experience with three "typical" children gives you enough knowledge to be an expert in the area of special needs. If she was a normal child then, we wouldn't have therapy four times a week and praying we can pay for it all. Instead we would have soccer, baseball and ballet to worry about. If she was normal, I wouldn't still be trying to potty train my 5 year old child and have boxes of pull-ups in the closet. If she was normal, I wouldn't be spending time and a lot of money to get the cutest shoes I can find, that will fit over AFOs. If she was normal, we wouldn't be spending time looking for just the right color for the wheelchair so that maybe her friends might think it is just a little bit cool and not just weird. If she was normal, my back wouldn't ache all the time because I wouldn't have to lift her and hold her and try to position her so that she can have a semi-normal experience with her siblings and peers. If she was normal, maybe you would treat her that way."
Thanks! I needed that!
