Let Them Make A Mess
This might sound counter-intuitive but letting children make a mess while eating actually aides their development. Innately, children are programmed to experience their surrounding with their mouth and hands.
Hence, it is important to allow them to make a mess with their food while eating. Squishing, smearing, throwing, etc. will allow them to build familiarity with different food you give to them, according to a pediatric feeding specialist Melanie Potock.
