I don't feed my daycare kids soup for this reason - it is messy! I also feed the little ones the yogurt because it usually ends up all over. Once I know they have mastered other foods then they get to do the yogurt, or I will feed them most of it and then let them try to get what is left off the bottom to lessen the mess. I am currently working on getting my 13 month old and 18 month old using a fork/spoon to eat. There is no reason for smooshing food. Be firm, say No, squeeze her hand gently to get her attention. Take the food away, cup away, sit with her and enforce eating nicely.
