Thanks for the update. How difficult and frustrating for you guys. Having PS in your DS' genes must also a weigh on your minds. Keep your mind open when you see the ped... so often mum knows best when all's said and done. My reading says tests are sometimes wrong - either way. I'd be a bit reassured if his condition doesn't yet worry the ped enough to go beyond "wait and see". Thinking of you & glad we didn't have to go thru this with our kids.
