A government study based on two national surveys by Mathew Greenwald and Associates reports that caregiving for young people can include, not only feeding, dressing, and medicating, but also toileting, bathing, and changing adult diapers. It is not unusual for these children to miss school in order to perform their caregiving duties. The emotional stress they carry can be even more harmful to them than the physical burdens. They are also more likely to be anxious and depressed.
