“…Although only 30 % of individuals with developmental disabilities (Palmer, Thompson, & Linscheid, 1975) are reported to have such feeding difficulties, prevalence among those with severe developmental disabilities has been reported to be as high as 80 % (Perske, Clifton, McClean, & Stein, 1977). Pediatric feeding disorders may occur for a number of reasons and may be related to medical concerns (e.g., gastroesophageal reflux); skill deficits or difficulties (e.g., difficulties swallowing or chewing); or due to a history of reinforcement of food refusal (Babbitt, et al, 1994;Bachmeyer, 2009;Piazza, 2008;Williams, Reigel, & Kerwin, 2009). In all likelihood, it may be a combination of these factors that results in the most severe of feeding problems (i.e., lack of sufficient intake to maintain good nutritional status).…”
