Ok, so she's had PND, severely. I've suffered myself, and know how demoralising it can be, but really, last night's episode -what were the scriptwriters thinking? They made her look ridiculous. Okay, so Joshua bumped his head by falling off the bed. He's hardly a delicate little thing though. Mine have done that numerous times, and I haven't gone charging up to A&E. Who really does that if it's a seemingly not serious bump.
And as for her going into meltdown when she got back and Casey had left the house with Freddie. What's the deal with Casey? I know Claire was counselling her so is she a bit bonkers? But anyway, Claire trusted her enough to leave Freddie with her, and you can be in A&E for hours, so Casey may well have gone for a walk/drive with the baby.
I honestly just thought it was ridiculous.
