According to Dr. Harvey Karp (Happiest Baby on the Block), forks are actually easier than spoons at that age, because of the mobility of the wrist. Toddlers develop the ability to pivot the wrist somewhere around 15-18 months. (same age they start turning doorknobs and bathtub faucets) - it's not a skill thing, it's to do with the way the bones grow. Babies can usually grab a pre-loaded spoon almost as soon as they start solids, because they use an overhand grip - but the scooping action and keeping the spoon flat have to wait till that wrist can turn.
Try her with those fat toddler forks that are not too sharp, she may be able to stab things and get used to the idea of utensils while her wrists are growing.
