Ahhh normal lah tu, lepas demam baby memang jadi lemah sikit dan feeding kurang, kesian dia, tubuh sedang recover. A few of my mum friends mentioned the same thing, their babies took a few days to get back to normal feeding rhythm after fever. The good news is usually they akan bounce back once they feel better, tapi kalau dah beberapa hari still kurang menyusu atau baby jadi lethargic, better check with your pediatrician ya just to be safe, just want to make sure dia okay and getting enough milk. In the meantime, offer la frequently even if dia tak banyak minum; the more dia latch, the faster balik feeding pattern dia. Jangan risau sangat, biasanya ni phase je.
