I have the SAME kid!!!!
I turn it around and do it to him! I say "Look S, baby is crying!"
"Oh my S, I think Jill wants to know when snack is"
"Hey S, the other kids want to know if they can play outside"
"S, Billy wants to know if his mom will be here soon"
"S, Gabe is playing blocks but didn't pick up his trucks first"
on and on and on.....
Drives him batty!
