I really like your sites Amelia, and I signed up quite a while ago. I'm afraid that I'm one of the affiliates that hasn't come across with the traffic though, and I'm not really sure why. I think I got seduced into promoting the larger multi-site sponsors because of the ease of chucking together quick mini sites to put on domains.
I don't know how you can get more traffic, but one idea was to try promoting your girls on the boring cooking teen pages. I thought that may create a bit of interest, but I'm not really a promoter of teens.
As a personal view, I think going to pps is the wrong thing for you, especially if your sites retain and get cross sales with credits. I can't really rationalise that view as I've not had any informative responses to my comments on the decline of the affilate role. Reading behind the comments I've seen, I think it's time for me to move away from the multi-site sponsors, and to focus more on sites like yours and Jels. I'm also going to try to avoid pps sponsors in favour of revshare with good rebillers like Linda Might.
I gather I'm not a typical affiliate though.
