No wonder she doesn’t have many people in her life, she is utterly draining. I genuinely don’t think she can be happy about anything because if she gets her way and they move abroad, you bet she’s going to be whinging about that too.
So many other families have a “normal” like that or worse. This is a temporary situation that the elder two children have dealt with before while the younger one doesn’t really know. What is life like for Isla and Lachlan? Pussyfooting around mum, shipped here, there and everywhere because she doesn’t want to be with them, constantly fighting for attention because their mum films everything and spends ages online whinging to people (some of whom will be an awful lot worse off than her).
And all this made worse because she knew what she signed up for when she had kids with a guy in the Navy!
