Hi Trista,
The
2016 Disney Dining Plan includes one (1) Quick-Service Meal, one (1) Snack and one (1) Table-Service Meal per person, per night of your package stay
for everyone in the party ages 3 and over.
As a result of this, if you have added the Disney Dining Plan to your vacation package, your 3-year old child will have their own Disney Dining Plan meal entitlements to be used during your stay. All unused meals and snacks will expire at midnight on your package reservation check-out date.
In my opinion, as your 3-year old child will have their own meal entitlements to use at Table-Service dining locations, you may as well use them.
The good news is that you will find most Table-Service restaurants to be very accommodating towards picky eaters. I should know as my now 13-year old son is still to this day a picky eater. There are lots of child friendly options available on the kids' menu at each dining location and if you are really struggling, your server may be able to request something simple such as a grilled cheese sandwich (which is not shown on the menu) as an alternative.
Wishing you a magical trip filled with memories which will last a lifetime!
