Let LO play with spoon during meal time, then encourage(asssit LO scoop food with spoon and put into his/her mouth) and cheer for LO he/she put the spoon into his/her mouth.
Eat together, so that LO will be able to see how we eat with spoon, LO will try to do the same. Refrain yourself from feeding though LO might takes awhile to eat by him/herself, give your LO some time. Be consistence and let your LO self feed everyday during meal time. Sometimes LO might use his/her hand, it’s ok, just remind him/her that he/her can use a spoon to eat just like us adult.
