The best I can suggest is 'to get out there' lol
Can you do the drinks at the local toddlers to meet & introduce yourself to parents?
I must admit to being surprised at the negative response Joshie got when she tried to do a flyer drop but saying that I recieved a business card through the door a few days ago from a local minder ,which I thought was a fab idea .. not sure if it was indescriminate drop (which could cost you lots of money !!) or hand picked knowing I had a youngster !
