If Jenny could have an ideal day, Eddie would be either with his grandparents for the day or with trusted friends. Jenny would have slept through the night undisturbed (still a rare event) and enjoyed a lie in (with Paul looking after Eddie until it was time for the boy to go to said grandparents or friends for the day).
Jenny would have breakfast cooked for her by Paul and the couple would spend the day walking, swimming, reading and doing all of these things leisurely in a way they can't since Eddie's birth. A nice meal out at the local pub would mark the end of the day (as Eddie would need picking up again afterwards).
And there would be no sign whatsoever of any kind of magic emerging in Jenny herself or being unleashed by Eileen or anyone else. Jenny would welcome that regardless of how the rest of the day went!
