Guess who?

In Indonesian we have been learning to say our age (in R-2 classes) and when our birthdays are (in Yr 3-6 classes). 

"Umur saya tujuh tahun" said the person who made this beautiful kue (cake).

Her older brother (Y2) said "Hari ulang tahun saya delapan November". 

Her younger brother (R5) said he was lima years old.

Can you work out whose work this is?
