The boys' bedtime routine is: 830pm, ready for bed, atropine drops for their eyes, we read stories or poems, or just talk silly stuff or make up a story where each of us takes turn to say 3 words, eg, I go "Once upon a" Brian continues, "time, there was" Sean goes, "a tortoise who" (I've banned the word tortoise). By 9pm, it's lights out till 7am the next day.
They usually chat with each other in the dark till 930pm, and laugh and giggle really loudly. I'll shout from wherever I am for them to Shut up, no more talking! If you can't wake up tomorrow morning, I'll cane (instead of wake) you up!
Two nights ago, I left them as usual, after we had each read 2 funny poems, and went to my room to surf the internet. But instead of chatting in normal voices, they've learnt to keep it really down. Whispering, and stifling their giggles and laughter.
Every 10 minutes or so, I would realise they were still awake, and shout out for them to sleep. It'd be quiet for a while until I realise they were still whispering and laughing. It was 10pm before they fell asleep. Luckily, they could wake up on time the next day or there would have been trouble.
