Kiss Feeding
babygaga.com, Tiny Fox Lab

Premastication, pre-chewing, or kiss feeding is the act of chewing food for the purpose of physically breaking it down in order to feed another that is incapable of masticating the food by themselves. This is often done by the mother or relatives of a baby to produce baby food capable of being consumed by the child during the weaning process.Tiny Fox Lab Facts
