Because of Piglet's congenital megaesophagus, her owner was holding her upright for 20 minutes after feeding every four hours.
My solution to keep Piglet upright was to cut a hole in the top of a lid of a tin container and fit it with a tubular stockinette
Piglet could poke her head and shoulders through to remain upright. Piglet has since grown into a laundry detergent container.
