Our son is scheduled for VT for the first time next week.

He's not been diagnosed with SPD, and I don't know how he's going to react, but he has had a long history of sound sensitivity, and recently he's been complaining about light sensitivity.

According to the doc, the outlook for his VT is excellent. (Pun intended.)

I hope the sensory melt-downing is a temporary hurdle for your DS, Heather123.
