My 1 yr 8 mos son dont usually hold his own food, like if u give him.biscuit he would ask u to feed him.instead.how cn i teach him on this? Tnx

Ask him to imitate you. Then show him how to hold the biscuit and putting it in his mouth. Join him while he's eating so he can follow your lead until such time that he's used to eating on his own.
