What are some good recipes for an underweight toddler?

Add butter,cream,and full fat dairy to recipes

are they not liking the food? do they not eat? my son wasn't wanting to eat certain things but finally i got smart and decided to treat him with a desert every time he ate everything on his plate. now that he has tried more foods he actually found out he likes more foods. and the deserts can be healthy such as yogurt, raisens, applesauce, ect.

chicken nuggets and fries come to mind...lol...really though, adding things like peanut butter, cheese, and full fat milk and yogurt are a good way to get in more calories and nutrients...ensure also makes a toddler version or you can fix him/her a glass of full fat milk with carnation instant breakfast...my toddler LOVES the carnation and it has helped him keep within normal weight. my son eats most any food and a lot of it, but has always been in the 25th percentile or below for weight (50th for height) until i added his morning breakfast shake.

how old and what weight? i do not really believe in fattening up babies and children. try your best to provide them with healthy options; )

if you have been advised by your care provider to do so, just add more calories to his diet. Such as butters, whole milk, etc. No need to add sugars and candies.
