And of course, there are foreign coins. Mr 9 has started collecting them. I once had a huge collection of various money from my travels, but they seem to have gone missing when we moved. However, I still occasionally get the odd coin in change when it goes straight to Mr 9's collection. Currently we are doing a tick-chart for him to work towards his goal of buying a coin book to store them in.
How do you entertain your kids when they are sick enough not to go to school but not quite sick enough for bed?
