Know-How Exchange : Advertising/PR

This is a new product for babies already being sold by established companies. It will stimulate their senses and be visually interesting to watch with music to it. It will have its own website. With no real advertising budget it needs to cut through all the clutter and make an impact on new potential customers: i.e. mothers and would-be mothers. Need ideas on creative, original, effective ways and means to get the message across to those potental customers.
In other words create a word of mouth buzz would be the most effective way to go, I believe. I read the book the Tipping Point. Be creative, daring and off the wall.
