It is clearly set out in her most recent grid post that J had a pre-op assessment yesterday and is in hospital in London today. Kaytee was out yesterday, which means somebody else was looking after J, whilst she was getting drunk the day before J has a risky procedure.
I accept that it was her 30th birthday and she should celebrate. But maybe, just maybe, she should be waiting until after J has recovered from his anaesthetic? Not to mention that the main justification for the begging earlier in the week was that she had nobody else to look after J. Now somebody else is clearly caring for him whilst she gets smashed the day before J has an invasive procedure involving significant risk.
Much like when she had a long-term partner who helped financially and with J’s care, this has been omitted from her main Insta-account because it doesn’t fit the narrative of her account. Her account is purely for exploiting J’s medical issues for pity donations. In order to maximise those donations she portrays herself as a single mum who is doing everything on her own and never has time away from J.
