Supper? Breakfast?

It is 3:00am. I have just finished pumping and o have also just devoured an anpan bun K had gotten for me earlier in the afternoon.

For some reason, my mouth (or was it my tummy?) told me to grab a red bean bun when I went out to the kitchen and I ended up having it for supper. 

Or is it breakfast since it is morning already?.....
