Very sad and ridiculous how some people could be so heartless. I hope you and your baby reunite very soon.
I'm pretty new to this area in Southern California (currently in Twentynine Palms, Ca). A couple months ago I learned of an online yard sale website that's pretty famous in this area. It is very similar to Craigslist, you can sell things, post "wanted" ads, etc. I've noticed several people post "lost dog" ads under the pet section, so I thought I'd mention this to you so that you could expand your search. I am registered on
