C.D.
Try putting out a snack tray with lots of nibbles. You can grate things like carrots, pear, apple and make little piles for him to taste. Can he eat nuts? My daughter loves pistachios, cashews, sunflower, and pumpkin seeds (all organic). She likes hummus too. And lately she likes to eat a bit of toasted bagel with cream cheese (maybe try non-dairy spread if you are trying to avoid dairy). String cheese is a possibility if you decide he can eat dairy. Can he eat butter? That is a nice high-calorie thing that you can add to bread or crackers. Sometimes my daughter will eat black olives. Blueberries and grapes are a favorite. Dried fruits, shredded coconut, granola, and popcorn. (My daughter is ALWAYS willing to eat freshly popped popcorn.) If you make the popcorn in a pan with a lid on the stove you can add some olive oil, walnut oil, or coconut oil for extra flavor and calories instead of butter.) Pear, apple, grape juice to get some extra calories down? My daughter eats best when she is distracted by other things... like when she is in the stroller or the bathtub. You might have to get creative with where you are feeding him. Hope this helps.
