How long do you think it'll be before the two young'uns will be sharing a bed? For sleeping obviously, like you said, it's a family show.
I think we're getting close.
Maybe 1 or 2 more updates watching the husband and wife deepen their platonic friendships with the 2 young girls in a wholesome family way.
Then maybe one of them gets introduced into the bed in a full time capacity, probably Lydia first. She's a servant and it's likely her roof may leak during the rainy weather .... can't have her sleeping in a wet bed. She must sleep with the MC and his wife, to keep dry ... well, dry'ish.
Then winter comes and it's far to cold for our friendly femsquire to sleep alone so she must also join the bed to share the warmth of the 3 already there.
Perhaps they should hug naked in a wholesome way because that's the easiest way to share body heat.
Friction also causes warmth so, for science, they should rub against each others bodies.
As it would also be too cold to get out of bed to bathe I would also suggest bed baths using the tongue so no one has to get up. Get those clean tongues in those dirty places in a pure family kinda way.
Yes, I believe that would make excellent viewing for the whole family.
Assuming that family are fans of Warburtons because it is the family that is into bread that stays together.
