i feed twice a day, when i get up & at dinner time and offer to go out often. Although Tilula doesnt always eat when i feed her... If they go in the xpen, maybe you should put it outside for potty time, if they are playing t much outside to think about pottying maybe take them out seperately & if one goes make sure the other smells to get the idea. Sometimes you have to let them have a couple accidents running free in the house to see where they prefer to go-if you want to choose proper placement for puppy pads, then when they learn to go to the pad you can move it near the door until they get the idea & basically take it away & when you see them sniffing for it you let them out. They have grass scented pads, you can soak up a little urine on a clean one so they can smell it & figure out what is going on. I never owned pets when my kids were small, the kids & husband were hard enough to train

& you wouldnt want the babies crawling on the pads. But normally using a couple different house training methods/options helps and as they get older enforcing the one you prefer. I use pads & have a pet door to a fenced yard plus remind her to go out often but Tilula still goes where she pleases about 5-10% of the time anyways. She is 2 yrs old. Yorkies... Good thing they are so cute
