17mth Old, Doesnt Likes To Bite On Food

My kid is 17 mth thus she should be able to bite well with her almost full teeth grown. However she has been quite choosy not wanting to bite on food since 16 months. (almost everything) Any help or suggestion. I do not want to overly mash food due to the nutrition fact and she has to learn how to eat properly. Any parents encounted and help?
