We will be using the analogue clock again with DS2 - I work at Parliament House and with over 2700 clocks in the building he quickly learnt what a "clock" was!

With DS1 I actually found it easier with analogue. I bought him a watch that had "quarter past" and "quarter to" and "half past" etc. You can buy "clock face" online from ELC toys dot com dot au - they're only $5.
