abdominal swelling

Overheard this interesting conversation in Mandarin by my dearest with my almost 3years old Aedan, driving back to SP from Penang.

Dearest and Aedan was seated behind, while I was driving.

Aedan: Mummy, why are you not wearing seatbelt?
Mummy: Mummy belly big mar...
Aedan: Oooo...
Mummy: So mummy fat can't wear seatbelt lor...
Aedan: But, mummy, daddy also fat, he can wear seatbelt. You see, he's wearing seatbelt.
Mummy/Me: (=,='')

Reminds me of the several 'F' we learnt in our medical school about differentials for abdominal swelling. Fluid, Flatus, Filthy Tumor, Fetus and Fat.

I guess it is time to adhere to some weight loss regime.
