A question for mama

Adults don't really have all the answers after my 3 years of experience in the world. I don't claim to be an expert but sometimes mummy can't seem to answer my questions.
You'll see what I mean.

Mama: Nate, you have to be brave when you go to school. When mummy was a child like you, mummy had to go to school too.
Nate: mummy, where's Nate nate when you go school?
Mama: hmmm.. (thinking of the easiest answer for a 3 yr old) you were still in mummy's tummy.
Nate: mummy, you go school pregnant your teacher scold you?
Mama: (in disbelief)can you repeat the question for mummy please?
Nate: your teacher scold you? You go school pregnant..
Mama: erm...

Seriously, don't you think my question made absolute sense??
