Yup, that was me that posted this list... As suggested early in this thread by someone, I just looked up the info on allears.net. I know the OP said that she had already done that and knew that there was limited number of TS restaurants who could accomodate this request, but as you can see... I took it upon myself to check (Taking all of 15 minutes to read every child TS menu) and voila... LOTS of choice. (to many in my opinion, since most restaurants only have 2 or 3 options, it is annoying to me that chicken fingers are so often the meal offered).
As OP is working with a Pediatrician I am actually kind of surprised that they are offering the suggestion of chicken fingers for most/all meals, due to feeding issues. I am a mother of twin boys that came very early, and have battled weight concerns (Need to fatten them up!) as well. Our pediatrician pointed out that children with eating issues often need variety presented in hopes that they get a balanced diet and nutrients- since they often dont eat enough in a day to put on healthy weight, it is vital to get the balance of nutirients. Adding unsalted butter to vegetables, or offering grilled chicken strips with rice or noodles (in butter) is far better to add fats and food into your child, than continuously offering nuggets. The amount of saturated fats they ingest on this type of diet is often worse for them than not eating at all. Our pediatrician and children's hospital also reminded me that a child has the inability to starve (Unless they have been diagnosed as "failure to thrive" in which case they would be hospitalized), and that they will eventually eat. So when they ARE ready to eat... to ensure that you add healthier fats (Full fat yogurt, cheese, butter, avocados, etc.) to their diet.
Just my two cents.... but in any event, I am glad that I was able to supply OP with the list of restaurants... so that her son can eat comfortably and enjoy the magic that is Disney.
