Pap boats were generally small open boat shaped vessels with pouring lips used to feed infants, children and invalids. "Pap" was a mixture of flour or bread boiled in water with other ingredients added when available including butter, milk and sweetners. Additional ingredients that were sometimes also added included wine and beer. Pap was also a mixture that was normally kept warm for long periods of time near bedsides in pap or food warmers (discussed elsewhere).
Pap boats were also made in silver and pewter (see photo below).
