WRT Frankie, she also said her boys didn't have a clue she was on the show. Given they are away filming for several weeks at a time, and she said her oldest was 18 (which would presumably make the youngest at the very most early teens, if not younger) the most obvious explanation for how they wouldn't notice their mum is around is they are all at boarding school, which for 4 kids simultaneously must be £££££.
Even if they're not and she's said she's on an extended business trip or something (although I think they have their phones taken off them?), having someone willing to look after 4 boys for several weeks is VERY supportive. That's a lot to ask even close family.
That doesn't mean she didn't struggle at all of course - even if financially stable, it doesn't mean that it's both emotionally exhausting being in sole care of 4 small children and physically draining, but it does perhaps explain why some of the contestants were more 'hungry' for the win - to me, the difference between dividing it between 2 rather than between 4 is "only", what, about 22 grand - while a lot of money it's a few months salary, so would be life improving rather than life changing.
Whereas, yes I can see if, for example it was the difference between being able to afford to try for a child or not it is, literally, life changing.
I'm torn on the 'as a mummy' bit - on one hand, I didn't love it, but on the other hand, some contestants have said they trusted each other on the basis of other shared commonalities - Joe said he trusted Minah as a fellow Scouser etc, Minah kept referring to the 'Sisterhood,' on other shows I've seen people say they've bonded with someone because of their shared ethnicity/job/cultural background etc. I also think she would have said exactly the same thing if it was, for example, Jake that she had discovered was the traitor rather than anything to do with Charlotte's infertility.
