I bought one of those fill-it-yourself calendars because I thought it would be nice to get out every year, and also because I don't quite fancy nearly 3yo having chocolate every day for a month (yes, yes, I'm sure that sounds anal to some but I'd rather keep a limit on it while she's too young to realise)
Anyway, now I can't think of anything to put in it except.... chocolate 
Any suggestions? I don't want to spend very much and put real toys in it - though we could do the odd one or two over the month. I'll do chocolate coins for some of the days. But what else might be exciting?
