Strong Smells-Picky Eater
My OT suggested this tip and it works, so I thought I would share. During our meal, we have a game of "try it". He gets to pick one new thing to try with each meal (we usually provide him with 2 options).
To get praise from our "try it" game, he simply has to hold the new item in his mouth for 2 seconds, (I count out loud 1, 2) then can spit it out. It is building his self confidence, and he is so willing to try new things. He has even decided to put the new item in his mouth for a second time, to really decided if he doesn't like it.
My OT says that each food may take 20 tries before he pallet / noise will be desensitized to the smell.
