Make or buy a taste-safe playdough recipe using edible ingredients like flour, salt, and water, since babies explore everything by mouth and standard craft playdough can be harmful if swallowed in large amounts. Supervise your baby closely the entire time they are playing, since even taste-safe dough should not be eaten in large quantities and constant attention lets you redirect them if needed. Let your baby squish, poke, and pull the dough freely rather than showing them how to make specific shapes, since open-ended exploration builds fine motor skills more effectively than following instructions at this age. Offer the dough on a easy-to-clean surface like a high chair tray or a plastic mat, since babies will inevitably drop, smear, and mix the dough into their surroundings. Add simple tools like a soft spoon or a small cup only once your baby is comfortable with the dough itself, since introducing too many new elements at once can be overwhelming. Store any leftover dough in an airtight container in the refrigerator and discard it after a few days or if it starts to smell off, since homemade dough can spoil, especially once it has been handled by little hands.
