My son is in feeding therapy. At first it was for sensory problems and texture aversion. We have fixed those but he still has motor function problem with chewing. The only thing he cant really chew is tough stuff like hamburger meat. He also eats very little at a time, wants to snack, and is on an appetite stimulant. I am so tired and discouraged. It is just so overwhelming. He was a 2 pound preemie so he is only 34 inches and 25 pounds. Has anyone been through this and have any advice?
