trust me, assisting with feeding = the phrase used for actually feeding people
Totem it does happen, but students do actually learn about feeding quite early on, plus they have a dedicated qualified mentor - there are not enough of those to go around volunteers
also worth remembering, students WANT TO BE THERE and have worked very hard to get there often studying health and social care or access to nursing courses first, so even a first year isn't some random off the street with no background
it takes patience to help a stroke victim regain the motor skills to feed themelves again, or to allow an elderly person with swallowing issues enough time to swallow each mouthful, NOT something that should be undertaken by anyone who isn't dedicated to giving good care
