Yet another approach...

Dear Nicky,

Today we met with Christine, a specialist with oral motor skills after our regular time at Stepping Stones. She had a number of suggestions for getting you to be a better eater. It was nice of Jessica to set this up for us, and I hope we didn't make a bad impression. Her take on your tongue and feeding issues is that it's not the tongue that's the problem but your jaw strength and coordination. So we've got one more thing to work on now. Isn't that great? Much of the time Mom and I feel you're doing perfectly fine on your own and you'll get there at your own pace. Other times we're scared to death, frankly, and I hope that's not rubbing off on you, my little boy.

Love,
Dad
