Final answer:
Children with Prader-Willi Syndrome commonly experience difficulty with feeding in infancy, along with developmental delays and cognitive deficits as they grow older.
Step-by-step explanation:
Children with Prader-Willi Syndrome (PWS) often have difficulty with feeding in infancy due to lack of muscle tone and poor sucking behavior. These early signs are indicative of the developmental challenges faced by infants with PWS. As children with PWS grow older, developmental delays between the ages of 6 and 12 years become apparent, and they may later develop excessive eating habits and cognitive deficits associated with the syndrome.
In general infant development, by ten months, an infant typically begins to crawl and show advanced motor skills, such as sitting unsupported and using a pincer grasp, and cognitive skills such as the beginnings of speech patterns and stranger anxiety. However, infants with PWS may experience significant delays in reaching these milestones due to their condition.
