Hmmm. Maybe it really is the case that while Daddy has Jesus in his heart, Sofie and Delaina have Baby Jesus in their hearts:
For He came to save all through means of Himself—all, I say, who through Him are born again to God—infants, and children, and boys, and youths, and old men. He therefore passed through every age, becoming an infant for infants, thus sanctifying infants; a child for children, thus sanctifying those who are of this age, being at the same time made to them an example of piety, righteousness, and submission; a youth for youths, becoming an example to youths, and thus sanctifying them for the Lord.
–St. Irenaeus of Lyons, Against Heresies, II.22.4
[We’ll leave aside his controversial comment that Jesus became an old man.–cdh]
