Waiting Children

Can someone please help me? I am currently looking at the waiting children lists of several agencies. On several occasions, I have asked one specific agency representative about the children. At this point, I have asked her about five children. I still have not found a child to adopt. I am afraid of being perceived as "shopping" for a child. My IA doctor tells me I'm doing nothing wrong, but I feel guilty about it. I almost think the agency rep is thinking "just pick one already!!" My question is: how many waiting children did any of you look at before making the decision? What made you make that decision? Thanks
