It is going to be a really tough time to start selling soap. The economy is down, and so are sales of anything considered "luxury".
I would think about 12 times before I marketed any soap for babies or small children. One bad reaction, and they are going to sue. Also, be sure to not claim ANYTHING other than that the soap will clean. No "for sensitive skin" even. The FDA takes a dim view of any medical claims.
I got into soapmaking because of eczema. And what I tell people I talk to about using my soap for someone with eczema is that it isn't anything special to my soap, it is just getting away from the detergents in commercial soap. And that I test my soap on myself and my family before sharing it out to others, but their allergies could be very different from ours. So, the ingredients are listed on the wrapper, and save that in case they have a reaction. That way, no one can claim I made any sort of claim of a "cure". When I make more soap, I am going to print that on a label for the back of the bar rather than just verbally telling someone.
