@morahmom – Exactly. Ultimately, Peninah’s actions were what set things in motion, but theoretically, there’s always at least good way and at least one bad way to go about doing something. I think Peninah, with good intentions, ended up choosing a less-than-ideal approach in motivating Channah to pray harder for a baby.
Of course, who am I to question Hashem’s decision to have things turn out this way? Gam zu letovah. Maybe by having things happen this way, not only did Channah become motivated to pray harder; maybe Peninah improved herself in some way as well. Perhaps it was concerning how to properly motivate a fellow Jew to pray with loads of kavannah. I bet she didn’t repeat that approach after that.
