1. Don't use preferred foods as a reinforcer. When children have very few preferred foods, we need to be careful about using these select foods to reinforce tastes of non-preferred foods at the risk of loosing the preferred food completely.
2. Generally it is better to set a routine than to "bribe" your children to eat. (ie: At the beginning of each meal, help your children explore the non-preferred foods, even if they don't eat them. Do this consistently, and soon your children will become used to the smell, sight and taste of these non-preferred foods. Then, offer them their meal. This way you are not bribing them, but simply adding a step to your mealtime routine.)
** Remember that it takes OVER 15 CONSECUTIVE presentations before your child will consistently chew and swallow a new/non-preferred food**
3. As always, avoid distractions while eating. If your child will only eat while walking around, with the TV on, or with toys on the highchair, then you will need to gradually reduce the dependence of these supports because this is not a functional way to eat. Often children use distractions to avoid taking part in mealtime.
4. Don't get in a power struggle. The main problem with reinforcing children for eating non-preferred foods, is that if they refuse even after you "bribe" them, then they have begun a power struggle, which is what you want to avoid with all children, but especially picky eaters.
Occasionally, it is necessary to use a preferred item or food as a reinforcer for trying a new food, however do not make this a habit. Most children will continue to try/eat a new food if they like the taste of that food, so a reinforcer each time is not always needed.
Seek help from an OT or Physician if you still have questions regarding reinforcements.
