I would have to imagine none of her kids are dyslexic or struggle reading as helping a child with any sort of issues surrounding reading/learning takes longer than a child who is confident and at higher level. During lockdown I would get my 3rd to read a chapter from a goosebumps each day and depending on chapter length could take up to an hour. Now I only have 6 so I'm not the largest of families but I am a bit of a helicopter parent and need to know where my kids are struggling and how we can help them( my daughter studying through her sqa's is another example) and I can't see either sue or Noel doing that, unless they practice the same as duggars and are Montessori teaching but I have never seen evidence of that on what they post!
That wouldn't bother the Radfords if their children were struggling, they still wouldn't do it. Education is not important to them. I doubt they'd even realise if their children are significantly behind as they don't do enough 1-1 stuff with them to ever pick up if there's a problem.
They appear to have struck lucky that Max, Oscar and Casper all appear naturally bright, they're often bragging about their academic achievements, but then it's no surprise given that Max has been diagnosed with (high-functioning) autism and the other two are clearly somewhere on the spectrum too from what we've seen.
However, it was plainly obvious during their pathetic attempts at 'home schooling' during lockdown that Hallie and Phoebe struggle, and yet they are either oblivious to it or not bothered. They seemed suprised that Phoebe was struggling to hold a pencil properly, which definitely suggests they never sit and colour etc with her, let alone do things like making cards etc to help her practise writing her name. Archie seems like he's going to struggle terribly when the time comes, as his speech and focus are both behind for his age, yet they won't bother to read with him. They never do (except the odd rare attempt for the benefit of the cameras, whenever they get criticised on here for not reading, and it's always so transparent as the concept is clearly alien to their feral bunch). Heidie or Ophelia (can't remember which) was actually offered a colouring book to 'read' the other day - "here do you want to read this?"
They're a disgrace in terms of how disinterested they are in their children's academic progress.
