When Wren gets a tooth, we don't see a good look at her tooth. In a later comic, we see Wren with a full set of teeth. How come we see Zoe and Hammie with their first tooth but not with Wren?
I'm guessing that was meant to be a Time Skip or because, when the strip debuted, it was mostly centered around the kids (Starting with Zoe) and then it slowly shifted to the family as a whole, so we'd see her older siblings' first tooth because, at the time, it was before the focus shifted a bit. Wren debuted after that shift.
