Regular old 148 gr wadcutters are about as good as anything, both for practice and defense.
The Speer Gold Dot 135 gr is made specifically for the 2 inch J-frame sized revolvers, but it is a bit more rambunctious than the factory wadcutters.
Hornady does make a pink-tipped Critical Defense load with .380 ballistics (95 gr at 800fps, IIRC), but Critical Defense bullets are designed to open early, so penetration suffers.
Reloading will allow you to make lightweight, low velocity loads a whole lot cheaper than the Hornadys. Once she gets used to the recoil of an Airweight J-frame, she can ease into the wadcutters or Gold Dots.
Some well-fitting squishy rubber grips like Pachmayr Compact Decelerators might help, too; the factory ones are a bit hard. Getting a proper grip is important in shooting these light guns well and enjoyably. They need to be well-centered with the hand high on the backstrap. The gun wants to squirm around with each shot, and it tends to creep up out of the hand, increasing perceived recoil with each shot.
