Just in time for Christmas though, plenty of time even for that dozy pair to get orders out!
Re: Issy not being allowed to walk to school, go out much by herself/with friends. I reckon Chris and Sarah know that the vlogs have made their girls a 'target' for people obsessed by the family. It's not so much the young ifam that are the problem, it's the adults - both male and female - who potentially pose a danger. Let's face it, a very lot of ifam and other people know where they live and where Issy goes to school - wouldn't be too hard to guess her route to/from school. To be fair, they have to take Esme anyway so it makes sense to take Issy too rather than her walk (not that I think she's probably been given the choice).
Re: the den, I haven't seen it as I don't watch the vlogs but I agree with
@Maisie842 . I'd imagine it provides a bit more privacy so maybe this is her subconscious way of hiding from anyone prowling round with a camera or her annoying younger sisters.
All the above doesn't explain the way they seem to be keeping her younger than her age (clothes, dolls etc.) though
I bet one of them is Thomas. Wonder if he did meet them that day?
