7 Yr old DD had a corker of a wobbly at bedtime (because she snuck downstairs to watch TV after getting ready for bed instead of letting me know so she missed out on a bedtime story because it was too late).
She was tired so she completely lost her shit, I kept admirably calm. I'm super proud of myself because I am also shattered and could have easily lost my temper but I didn't and just calmly told her that she had chosen telly over a story and that was that, but if she stopped screaming at me she could have a cuddle.
Eventually got her calm, tucked her in, came to bed myself but oof. It was just ugly in a way only an overtired child can be and I just can't relax and sleep.
