Yup photography wanting to book an appointment for your new baby. I told them my new baby keeps me up all night so photography is the last thing on my mind but they don't give up easily!
I think it may be a free photography number. Someone may have entered your name (or new born's?) name on their website and they come to take a free pic. Canadian Baby Photographers...http://www.canadianbaby.com/home.html
