I honestly think she’s terrified to be on her own with the kids for any length of time that they are awake. I think she “loved” the idea of being a parent but the reality is not the same as the idea and often brutal (having a baby with silent reflux/doesn’t sleep/feeling issues is hard, been there done that) and the insta perfect bullshit propigated by the influencer mums makes it seem like it’s all easy and perfect when we all know in reality that parenting can be amazing but also bloody hard and messy.
She’s got massive mental health issues - armchair diagnosis time : an unresolved issue with food, probably high anxiety, possibly a form of adhd, and probably some form of depression. She’s never dealt with any of those things properly and now can’t handle life and two humans who need proper parenting. I suspect all is not well between her and Rob at all, and if the man has any sense he will get the snip before Sarah can make him get her pregnant again.
She’d be better off in Scotland near her family because at least her parents would make sure the kids did more normal, aka just playing and being kids, but sadly, because suspect she’s viewed as very fragile and they are scared to confront her, none of her family will say anything until something really bad happens or she has a mental breakdown. Rob ain’t leaving the navy any time soon, he absolutely doesn’t want to be at home full time around her, but again, he’s probably too scared to actually tell her.
She’s not right at all and needs help. Sadly it won’t happen any time soon.
