When it's dinner time I sing 'dinner, dinner, dinner, dinner...' to which ds answers 'batman, batman, batman.
If either dc is pestering for something or getting in a tiz about something I always say to them, 'Don't panic Captain Mainwaring!'
My brother and I used to bark and meow tip each other. I'd say 'Meow,' like a cat and he'd bark like a dog. We'd do that a couple of times until I made that hissy rarrww noise that a cat makes and then he'd make a noise like a frightened dog running away.
When my dc tell me they're hungry I tell them I'm Poland and that it's nice to meet them. If they tell me they're thirsty I say I'm Friday. Dd, 3, replies with, 'I want you to get me a drink then, Friday!'
If I give my dc anything and they don't say please or thank you I ask them what the magic word is. They say please or thank you and I say, 'No, abracadabra!'
