This is supposed to be a touching children’s story, a tale of family love that comes full circle in a bitter-sweet irony, but, frankly, I found it to be…creepy. I get what it was going for, but the sentimental effect is kind of lost when we go from loving mom of infant and toddler to weirdly obsessed stalker mom of teenager and adult. There's a great country song that communicates the idea this was going for (and failed to convey). I can't remember what it's called, but it's about a son who is guided by his father and then must guide his father in old age.

One note - a child may possibly find the whole rocking the older kid / teenager / adult thing funny rather than creepy, because of the incongruity. If it seemed aimed at funny, I might have thought it so; but it seemed aimed at touching, and so just came off disturbing.
