It's 7.15pm. 6yo, who is usually in bath/pyjamas at this time, announces she is hungry.
Parent A - I'll get you some grapes
Parent B - Grapes? It's bedtime! Sugar/Not right before brushing your teeth etc At the most maybe a glass of milk.
Parent A - Yes you're right, too much sugar... takes 6yo in to kitchen and DD gets some milk.
DD comes upstairs grinning that sly grin and Parent B says OK now? DD says Yes that glass of milk really helped.
Parent B - What else?
DD - Parent A also gave me a bit of that cake...
Is Parent A a massive undermining shit? Or AIBU?!
