Load up on calories 1
Infants and children who show failure to thrive (FTT) will need 150% of the recommended daily caloric intake for their expected (not actual) weight. In infants this can be accomplished by concentrating formula or adding rice cereal to pureed foods. In toddlers, adding fats such as cheese, butter or peanut butter to common toddler foods can help.
