I agree with Alaska to reduce her kitchen space area.
I've also read elsewhere that if you're still in the beginning stages of pad training (side ramble: even when they're trained at the breeder's, they may still need to adjust in your home - and if taken elsewhere, the training again, goes out the window), try placing pee pads all over the small section of your kitchen.
For example, give her isolated space of 4 pee pads plus her bed. Lay out 4 pads. After a week, see if she has a preference to pee in certain areas. If there's one pad she never pees on, you take that pad away from that spot. Then the following week take away another pad she doesn't pee on (granted she didn't have accidents on the pad-less area. Then again after that, until you have one pad left.
