She might be too young still but instead of waiting to find her squatting, try her on a relaxed schedule and see how that goes. If she is dry when she wakes in the morning or from a nap, take her straight to the potty and let her sit there for a while. If she goes, take her again in 1/2 hr. If she goes that time then take her in another 1/2 hr. If not, take her back in 5 or 10 mins and every 5/10 mins till she does go then back to the 1/2 hr rotation again. If she doesn't want to sit on the potty, don't make her. And don't ask her if she has to go, tell her it's time to try to go potty. If you ask, the answer will be no and 1 min later she will have peed! lol This is how I did it with my son and he was trained by 2 1/2 yrs old and it only took less than 6 months to do it. I followed his cues too. If he gave me grief about going pee then I didn't make him. He would got a week or two without going and then all of a sudden want to go again for a week or two. But every time he would want to pee in the potty he got better about learning his body signals each time.
I also found that a potty chair that sits low to the floor seems to help with them going poop in the potty too. It puts them in kind of a squat position which seems to help with the pushing part. I used one from IKEA which is very similar to the small one from Baby Bjorn.
Good luck!
