I thought he was referring to Emma, the child, and product or manifestation, of Snow’s and Charming’s true love for each other. He was getting all of his ducks aligned in a row because he knew what was coming. At that point, the curse was completed because he had already used the drop of the potion on the parchment. He then needed Charming to put the remaining potion in the belly of the beast to protect the rest for the coming battle. He needed Snow and Charming to come together and conceive the Savior who could one day break the curse. He knew everything that he was doing.
