DayTimer FamilyPlus Planner
I just bought this one for the second year in a row. You can get it at Walmart for $15. I love the weekly page layout - it's definitely what won me to try out this planner. Each child gets a column, there are plenty of checklists and meal planner section is super helpful.
The downside is that it's plain. You can add stickers/washi etc, though I don't do that as often as I'd like. I love the price, especially after trying an Erin Condren the year before and not using it much.
