Children is like a clock. When the time comes they react accordingly. So, what stage are yours in?

Lun is currently the chatter box. He would constantly asking you why, what, how.
Like a broken radio who repeatedly singing the same song over and over again.

He would go.

Lun: 妈咪,你今天做什么? (Mum, what did you do today?)
Me: 早上,上班.对着电脑做工. (working in front of the computer.)

He will pause for a while, then come back again asking the same question.

Lun: 妈咪,你今天早上做什么? (Mum, what did you do today?)
Me: 做工咯.(Working.)

Again, asking the same question after a short pause.

Lun: 妈咪,你今天做什么? (Mum, what did you do today?)
Me: 早上,做工; 晚上回来陪你玩， (Work in the morning, came back at night to play with you.)
你呢？你今天做了什么?(How about you? What did you do today?)

Lun:我做fireman.搭屋子．hmm…(I was a fireman, i’ve build a house.)
Me:傍晚呢？有到公园去吗？(How about evening? Did you go to the park?)
Lun:有，啊公带我去公园做工．我是Construction worker. ( yes, grandpa bring me there, I work as a construction worker.)

 Lun: 妈咪,你今天做什么? (Mum, what did you do today?)

until he got fed up himself. Then pass on to the next question.
What is that? pointing to the ceiling or other stuff etc….
