So far this month... (Yes, I realize that we are only 5 days into the month, lol!) our menu planning has worked out well. We have stuck to the menu, ate the left overs on left over night and have grocery shopped according to the list that was made from..... the MENU!
Another great part of the menu is that the last couple of days, we have lost the "What are we going to eat for dinner?" stress. The night before I take out the meat to defrost for the next night. When we get home from school and work, the menu is right there, telling me what it is that I am making. Because I wrote the menu with our school/work/extra-curricular activities in mind, I am not trying to cook something that takes 2 hours when I only have 30 minutes.
So, although we have only been doing it for 5 days, it seems to be working out well for my family. The children love being able to look on the fridge door and see what they are having for dinner. It is something that I plan on doing every month from here on out.
