Do they only have a single room, why is the baby in every frame as an adult?
Also, there's something to be said about her completely changing her personality and how that would actually strain the relationship - I assume the husband liked her being "too cool for school" and acting above it all, but now she's a clingy lovey-dovey girl and acting in a way she would have previously never done. Perhaps he doesn't like public displays of affection either?
Still, if I stop trying to be some smug big brain critic, this is cute.
