"Well, I imagine it used to be, a very long time ago. But now we humans have neatly sorted things into 'food' and 'not food' categories, so if I didn't know if something were edible I could check with someone else."
"There are ways to test it - smelling and tasting before actually eating, rubbing a bit on your skin to see if it reacts badly, that sort of thing. But for every edible food, I imagine that there was at least one soul who said, 'I don't know what this is, but I'm going to try to eat it.'"
Lynn starts looking for places that Astrid can go swimming in privacy, considering its necessity. She considers the ocean, but the openness of that option makes her nervous. A proper pool does the same, so she looks into other options. Eventually, after some work and a large amount of time, she finds an out of the way pond that is open to swimmers, but not visited often. Especially early in the morning.
"Astrid," she says, one day. "Do you want to go swimming? I found a place, if you'd like to."
A few days later, Astrid is equipped with a towel and a swimsuit (that she picked out, Lynn has little to no taste for fashion) and brought to the pond to try out swimming. Lynn is similarly dressed.
"Any 'do not touch' coming from the pond?" she asks her daughter. She's learned by now to just - accept the weirdness.
To the water she goes. She wades in, untroubled by the cold water.
"Humans don't start out with the ability to swim automatically. So just because you can't immediately might not mean you will never be able to."
"What we're going to do first is see if you can float on your back. Sounds good?"
"Then I will be right here, and I will make sure that you don't sink. I promise I'll do everything I can to make sure nothing happens to you."
"It helps if you take a deep breath, but it's the sort of thing that is - hard to explain."
Astrid takes a deep breath. She sits down on the bottom of the shallow pond end, and attempts to lean back onto the water.
Lynn moves beside her, to help if there's any sign of panic or if there's something she can correct. Right now, though, she's rather proud of her daughter for being brave.
Astrid isn't panicking, but she's not mastering floating either. It doesn't seem to be a buoyancy problem, just a skill problem. She goes on holding her breath when her head dunks underwater and comes up with her hair plastered over her face.
She carefully corrects some of the obvious skill mistakes, and says reassuringly, "You can float already, see?"
"You are a floating thing!" agrees Lynn, grinning. "If you like swimming then we can try the public pool or the ocean, or we can stick to this pond. Essentially, if you enjoy it I will work to find ways you can do it."
