I agree, if you can get her foot into the skate, they are fine. Once she stands up, if the skates are getting too small, they will pinch or hurt real bad . . especially when she stands up or skates. Only ask her if her feet hurt once she's standing up. An old trick on "too tight" is to take out the insole.
Usually, skate shops keep plenty of little sized, beginner to intermediate skates in stock, but you may want to check as new styels/new year could have them out of stock (if you really think she's getting too close).
Another clue is to look at her laces, are they super wide apart? (But, that may not work if her feet are narrow to begin with and she's in a standard sized boot).
