climb up the staircase

What Ee Shuen did last Thursday in Gong gong & Popo's house?
She climbed up the staircase for 6-7 times in a day.


She reached 1st floor on her own. When she's climbing up, somebody have to follow her at the back.
That night, she slept through the whole night till the next morning 7am. I think she's too tired climbing up the staricase during daytime!
