Lots of great advice already!

Noticed you are in Oshawa - most Ontario Early Years centres have 'home childcare binders' for parents using the 'well baby clinics' and other services on maternity leave to peruse when returning to work ... if yours does not have one perhaps suggesting this would be a valuable resource!

I know it is a ways off yet - however Halloween is a great time to get the word out ... put a little business card with all your trick or treater's bags

Postcards on Vista print are VERY REASONABLE seriously often FREE and than just shipping and handling to be like less than $0.03 a postcard and very professional looking ... go for a walk and put some in mailboxes - put a tiny tag line on there 'reduce, reuse recycle - if you do not need childcare please pass me on to someone who might' ... post them on Community boards at grocery stores, libraries and so forth?
