I switched back to this calendar, after a year with the grufallo one, but was sad to see that the fold down cardboard edge and slider, that neatly hods back your previous months, has been removed and you not just have a small unreinforced punched hole to put over a nail. I can see the advantage but I am not confident of the durability.
Having said all that the calendar is bright and shows one whole month at a time with 5 columns. The boxes are not vast but I have never had any trouble fitting everything in. If you do want to write a lot, maybe look at a weekly family planner.
Lots of stickers to decorate the pages and the days and some summary tabs at the back, including a very handy year planner for 2014 and extra notes, The bottom part of the calendar (where you can see Sizzles) is a pocket for putting handy bits of paper and keeping your pen.
My only other complaint would be, that it would be nice if it included the last month of the previous year, e.g. Dec 2012, so that us mums have got a whole month to get ourselves sorted and switch over to the new calendar, instead of having to wait until 1 Jan. Just a thought.
