What they say:

"Nar-na"

Translation:

I don't give a crap whether you get the red or the blue, Mum. I'll be wiping my sticky banana fingers into it regardless.

What they say [at dinner]:

"Ahhhhhh, NO!"

TRANSLATION:

"No, I don't want cucumber, or chicken, or sausages, or chips. What's that you've got? Cucumber, chicken, sausages and chips? That looks nice, I'll have some of that, but not the stuff from my plate.."

What they say:

"Oh, wow!"

TRANSLATION:

Look at this huge multi-pack of branflakes/dog food/tuna. You want this in your trolley, don't you guys? I thought so, let me just get a few packs and put them in when you're not looking.

What they say [in trolley]:

*has nuclear-force tantrum*

TRANSLATION:

Get me out of this mofo-ing trolley right now. Don't try and carry me either, I want to be able to see everything up close and pull it all off the shelves and wait, are we near the toilet paper? YES, I WANT TO HIDE BEHIND ALL THE PACKETS.

What they say:

"Choo choo!"

Translation:

"Mum, there's a train, there's a train, there's a train outside. There's a train, Can I go on the train!?"

What they say [at Starbucks]:

"Num num"

Translation:

I know you bought me a healthy delicious snack, but I'd rather smother my face with whipped cream and eat your marshmallows, or I can scream until you buy me a donut? Your choice.

What they say:

"'Ook, 'ook"

Translation:

Look, Mum, a giant rainbow bear/1000 pack of cotton buds/anything with Peppa Pig's face on it!! Let's get one!

What they say:

*silence*

Translation:

Perhaps a nap? Nah, I think I'll see how much of a mess I can get into with this bright orange mango smoothie Mum's given me to keep me occupied. Maybe then we'll have to go home to change...
