Natural Baby Products

Hi all, I would really appreciate your input! I am a preschool teacher and throughout the years I've had a lot of parents ask about the best natural, chemical-free, organic baby products (baby shampoo, baby massage oil, nappy cream, nipple creams, baby laundry wash etc) and I have noticed that a lot of the 'natural' products you can buy still contain a lot of nasty stuff. Just wondering if there would be a market for handmade baby-care products (all-natural, for sensitive skin, environmentally friendly) for an affordable price? Is this something you as a parent would be interested in buying? I hoping there will be a pregnancy range, baby range and giftware/kids range Thanks so much for your input :)
