Homeschool her, have a television but no connection to TV channels - she can only watch films and tv shows from the selection of DVDs and videos I've made avaliable to her, and ideally she'll only watch them when she's with me and/or her Mother (so we can bond together and we can explain things in the movie/show that she doesn't understand). This way she will be free of degenerate shit that corrupts people's minds today, and she's less likely to become a lazy couch-potato.
I'll try to get her interested in reading, by reading to her often, and buying her several books, ideally pretty editions which catch the eye of children (that doesn't mean it has to be infantile shit - you can get more mature shit that is still eye-catching, such as pic related). As a Brit/pol/ak, Arthur Mee's children's encyclopedia seems like a good choice as it encourages British patriotism and explains the inferiority of other races. It also caused Muslim riots for their depiction of Mohammed, and the book apparently was a big inspiration for David Starkey (Based British historian who BTFOs SJWs).
I'll take her to some outside classes/groups so she can make friends, and try to encourage her with the right sorts of people. I will flip my shit if she finds a xeno boy or otherwise degenerate person.
In reality though I'll either have to give in to my wife by giving her access to degeneracy and freedom from discipline (as the wife will probably think it cruel even though it's for her own good), or I'll stand up for my principles and the wife will divorce me, take the kid and all my money. Either way the girl is fucked.
Thanks [current year].
