Considering Destiny's family's former routine, the most successful way to create change and start having family dinners would be option C: Begin with one family dinner a week and go from there.
Option A, scheduling family dinners every night from now on, might be too drastic of a change for Destiny's family, especially if they are not used to having regular family dinners. It could lead to resistance and difficulty in maintaining the new routine.
Option B, having one month's worth of nightly family dinners as a goal, could be overwhelming and challenging to sustain, especially if they are not accustomed to this routine. It's important to start with a realistic and achievable goal to increase the likelihood of success.
Option D, promising to make every meal herself if the whole family attends, puts too much pressure and responsibility solely on Destiny. It's essential to involve and engage all family members in the process of creating change and having family dinners.
By starting with one family dinner a week, Destiny's family can gradually adjust to the new routine and experience the benefits of eating together. Once they become more comfortable and see the positive impact, they can gradually increase the frequency of family dinners if they desire. This approach allows for a smoother transition and higher chances of long-term success in establishing regular family dinners.
I hope this helps! :)
