This is from channel "Motivation for Mom's". Notice the misspelling of "moms", which shouldn't have an apostrophe.
But let's ignore that for now.

She sounds very much like Christopher, and the title card of the video is the identical style to Christopher's. I believe this whole thing was probably his idea. Not sure what her angle is. Maybe to sell her "divorce" book that she wrote awhile back?
Really appears she's reading a prepared speech. You can tell between the 3 and 4 minute mark where she oddly pauses between some words.
Her story involving Christopher starts at 9:32.
At 11:13 she talks about the custody battle she had with her ex-husband.
She claims "my daughter goes back and forth between my ex and I" at around the 17 minute mark. I don't believe that. We've never seen her in any of the videos, and she lives 2000 miles away from her daughter. In most custody cases, both parents are required to stay in state if they wish to maintain any custody of the child. They don't ship kids back and forth 2000 miles to see each parent, especially if one parent voluntarilt gets up and moves away as Stacy did.
