I noticed, too, that in the comments after the 'trailer" one--one of Jolene's fellow cast members thanks her for making the trailer. Not concrete proof, but if you do the math, these are probably Jolene's videos, taken on her phone or her husband's or something. Since the Facebook page is brand new, these performances were probably the opening night. Her husband and others probably came to see her perform, and it would make sense that they would bring the baby. "Look, there's mommy." That kind of thing.
ETA: I just rewatched the trailer and paused on the end credit thingy. Jolene put her own name in "Edited by" and "Director of photography" is listed as Robin Rapino.
These are indeed Jolene's videos.
