Answer:
Emily has delayed oral-motor skills
Step-by-step explanation:
Emily doesn't feed herself and cannot even hold her water bottle, but she bangs and play with a spoon.
The action of paying and banging with a spoon signifies that she does have motor skills, but they are not fully developed to the point which she can consciously hold her water bottle to feed.
Furthermore, the fact that Emily gags when offered crackers proves that she doesn't like crackers and cannot express her disinterest in a coherent oral form because gagging is a muffled oral expression that signifies her oral skill are not fully developed.
