Help to design a range of teething toys & jewellery for mums to wear & babies to chew

Information for the business: New business I am setting up to offer help to parents with teething babies. There will be a range of products that babies can chew on
Industry: Healthcare
Design details: I want to bring out a range of products. Ideally I want them made in natural latex (see http://www.mummyoftwo.com/review-hevea-natural-panda-teether/) There will be a teether in a similar design to this but other animals. They need to be weel designed to allow babies to chew and reach all teeth, have texture to help their gums, be strong and safe. Latex is natural and naturally antibactirial so a good material to use. It is appealing to parents.

In addition to this there will be a range of jewellery that mothers wear and the babies chew on. These will be made in either silicone or natural latex. Examples of others doing this are: http://www.smartmomjewelry.com/, http://www.jellystonedesigns.com/, http://www.chewbeads.com/ http://www.gumigem.co.uk/

I would need to work with the designer and agree a range and materials etc.
Ideas for the visual style: natural, fun, safe
Urls to draw inspiration from: http://heveababy.com/en/teething/12-panda-teether.html http://www.smartmomjewelry.com/, http://www.jellystonedesigns.com/, http://www.chewbeads.com/ http://www.gumigem.co.uk/ http://www.makeuwell.com.au/makeuwell-natural-rubber-teether.html http://www.notonthehighstreet.com/mushroomandco/product/teething-toy-apple?utm_source=GoogleShopping&utm_medium=Baby%20&%20Child&utm_campaign=285706&gclid=CI7G4dXMirwCFQcTwwod3kYAFA
Extra notes: I want to start with a number of teething toys and look at a small range of jewellery and then over time work with the designer to increase this range. I have the company logo and name sorted.

I need to understant the costs and time requirements. I also need to ensure that the products meet the safety standards as they will be marketed to infants under 36 months
