As zei in the book, he can switch shapes like Tonks, so he might've inherited meer from Tonks then Lupin, so he'll be meer on the human side during the full-moon.
I don't think he'll be a full were-wolf, he wasn't bitten, his father was. There's still a lot of human in him, especialy considering Lupin was turned meer and meer human during his transformation door the company of James P, Sirius and Peter Pettigrew. I don't know if that stayed with him in his later years thought.
Neither do I think that he'll be human during full-moon.
Is he going to be a Bill Weasley type? No. I think there's meer were-wolf in him then that.
What about a guy in the shape of a were-wolf but still human thoughts? of the opposite. To me that's the best theory.
Maybe a half-human half-were-wolf transformation? Like a snout and claws but no ears and tail? Something like that.
What about silver? Will he still react to silver? The vennom that turns one to a were-wolf makes him react to silver, but he has meer like a demiportion of the stuff, so maybe he'll only react if he wears it for a long, long time.
As u know if you've finsihed Harry Potter 7, Teddy was in Harry's care after the death of his parents (grr). So its Harry's problem. Who would be ebtter to deal with a half-werewolf toddler then a guy who defeated Voldy and has all-acces to Hermione? Teddy Lupin msot likely had a pretty nice childhood.
