Just started the process

I'm very new at this process and came across this site. I was hoping to get feedback from people who have actually gone through the process. Any info would be greatly appreciated:) Currently I have turned in all paperwork and have completed 2 classes. My overall goal is to foster adopt a female infant. I'm a single parent who just wants one more child, but does not want to go through the pregnancy process again. Since I'm single it seems this is my only way for now. Is it possible? After the second class I'm kind of getting a little discouraged that it is not be able to be placed with a infant. As anyone had any success with this in DFW Texas area I would love to here your process. Thanks:)
