Hi! I'm just curious about this issue. Is it safe to breastfeed when a mum is sick or having a fever? I've experienced this twice. On the first instance, I was afraid that my daughter might contract the influenza which I was having at that time, so I didn't offer my breast. Instead, I let her feed through her bottle. On the second occasion, I was having a fever at 39 degrees Celsius, but because my son was very fussy when drinking milk from the bottle, I still breastfed him.
