Oh, I get you. My guessing is that her child alter is out so that other parts of her can deal with what she's going through right now.
I just got an idea, what if you tell your partner's child alter a story and in that way you tell other parts of your wife what you wanna tell her?
You guys may sit and color a book, or in front a fireplace eating marshmallows and there you could be a story teller.
Create the story you want her to know, in a fantastical, child-like way, that would transmit what you want. And announce the story to everyone who is able to listen.
So ,you could say:
"I'm gonna tell you a fantastic story that happened many, many years ago. I want you, all parts of you, and all parts of me, and everyone who might be listening right now to pay close attention. And if any of you think someone else may benefit from the story, you could let them know too."
In a way you feel comfortable, and that would make your partner's child alter feel comfortable as well.
If she asks you why do you say so, you could answer 'coz there are fantastical beings every where who might wanna listen to the story and enjoy it.
And later it could go as something like:
"Once upon a time, there was a little girl, who was guarded by many wise people. These people had little contact with the outside world, and the little girl was the one who every day would go out and look for food and get to know the world. One day she met another fantastic girl, with whom she played and watched TV. Every day she would go the wise people and tell her how much fun the two of them had had together. After some days, the little girl that was guarded by many wise people, saw that the other little girl was sad, and didn't know how to help her. So immediately, she went to talk to the wise people she trusted, looking for help. Among them, one wise woman, full of love, reached for her and explained that maybe the other little girl was feeling lonely, that maybe she needed a motherly hug. So she the wise woman offer to accompany next time she would go and visit her..."
