Answer:
It has to do with cost, portion control and child personality training
Step-by-step explanation:
1. Portion Control: Parents often give their children so much more to eat than they can, when meals are presented pre-plated and this can lead to waste, which would have been avoided in a family-style meal where each child can pick for themselves as much as they know they can eat.
2. Cost Control: Pre-plated meals because of their nature of already-defined-portions could help parents budgeting as against when children begin to pick so much more portions of fish at meal time, than they do vegetables; which can spike the cost of each meal
3. Personality Training: In pre-plated meals, the decision making is in the hands of the parent but in the family style meals, the child is beginning to learn how to make choices and decisions, early enough in life; which have have huge leadership benefits at the work place and personally, later in life.
