Baa Baa Black Sheep

How does Isaac sing 'Baa Baa Black Sheep'?

He goes, "Baa Baa Black Sheep, happy and you know. Yes sir, yes sir, three bags full."

Less Than Zero

Andrew asked Isaac what was seven minus nine.

Isaac thought a while and said, "Megative two."

Seven

We brought Andrew kayaking at the Kallang River. Isaac wanted to kayak as well but he couldn't as he was not yet seven.

He said, "I wish I was born in 2017, so now I will be seven and I can go kayaking."

Kimi no Kickapoo

Isaac asked me, "Why can't Kimi drink Kickapoo?"

Before I could answer, Isaac said, "I think Kimi is thinking, I can't drink Kickapoo because... I will die! So, I won't drink."

The Colour of Milk

Sean told Isaac that brown cows give chocolate milk and pink cows give strawberry milk.

Isaac said, "Transparent cows give water."

How Many Years Older?

I told Isaac that Sarah was fifteen years older than him.

He asked me how many years older than he was Sophie.

I told him that Sarah was three years older Sophie.

He thought for a while and said, "Then Sophie is twelve years older than me". 

Isaac is six.

Tens & Ones

Isaac asked me how many tens and ones make one hundred.

I didn't quite understand what he meant, so he clarified, "Nine tens and ten ones!"

Catching on, I asked him, "So if it is eight tens, then how many ones?"

He thought for a while and shouted, "Twenty ones!"
