I wish I had eight days in a week! I might be tempted to use that 8th day to sleep though!
I'm a listmaker. I also have a diary and an iphone.
I use reminders on my iphone a lot as well as the calendar. I know I can somehow sync an online calendar with my iphone but I'm not clever enough to have worked out how exactly.
My diary is a Mum's Memory there are a couple of small things I don't like about it but mostly it works for me. I spent a long time looking at diaries before buying the MM. I've had the MM 2 years in a row now.
One of my main problems is that it's just too big to carry around with me. So it stays on my desk and I check it every day and try to write appointments in straight away.
I also bought an InnerB Mums agenda in a lovely pink but I haven't actually used it yet. If MM ever stops being made then I'll buy a refill for the IB.
A friend of mine made her own diary using a Levenger journal and some ideas from DIYPlanner.
Some other diaries I considered were-
Tiny Me Design your own
There are so many family organisers available. I've tried a few different things, I have a magnetic whiteboard family planner but I don't really use it.
I've made our own family folder with ideas from some of these sites-
Did You Remember the Milk?
FlyladyOrganise your life
I keep our takeaway menus in it as well as school papers like tuckshop lists, uniform price lists etc.
There's also a section for family holiday ideas and a section for menu planning.
I also have copies of any organising printables I find on the net.
For menu planning I'm currently using a 5 week planner from Picklebums blog.
Kate has lots of useful printables on her blog (as well as some great family recipes!).
I find working our meals 5 weeks ahead works well for us at the moment. I can write a shopping list each week a lot quicker and I can swap meals around if I need to.
These things all help me stay organised to some extent but I could still do with that extra day!
