See Spot Run
Had this idea based on the fact that babies are incredibly attracted to high contrast patterns. In particular, my baby is enraptured by the book “Spots and Dots”.
Originally the idea was for the baby to be pulling away from one parent towards the other whose skin is covered in high-contrast pattern, with a caption to the effect of “I have no idea why he prefers me”, but I saw an opportunity to use/abuse the Distracted Boyfriend meme and jumped on it.
