Proper not Purple

Scene:
Kay left asleep in my arms. Hence I asked helper to prepare the bed.

Me: Auntie, please get pillow and bolster for Kk, let her sleep on my bed first.
Helper: Got the tiny pillow (beanie pillow) on your bed for her already.
Me: No, Auntie. That is not a proper pillow. Please get Kk’s proper pillow and bolster.
Helper: *looks at me as if a bit unhappy with instructions given*

A few minutes later…

Helper: Mum, I prepare the bed already. But no purple pillow, pink can?
Me: *looks at helper, shakes head* I never ask for purple pillow, I asked for PROPER pillow.
Helper: *laughs*

Question:
Is it my pronunciation skill or her hearing issue?? I don’t know lah….
