My son has a high pallete also. His was so high that i was unable to breastfeed him. We brought him to speech pathology an we hooked up with a swallow specialist in the area. They recommended us to use Haberman (a.k.a. Special Needs) Feeders. He has been doing so good since he has been using them. You can find them at http://www.motheringfromtheheart.com/catalog/150ml%20Habe...
they are a little pricey but he started eating so much better after. I hope this helps you!
