Sabar ya, mummy! Memang scary but baby 8 bulan usually okay punya, a few of my mum friends' babies kena COVID, demam 2-3 hari then baik la, some with mild cough je. The fact that you've already checked with the hospital is good; just keep monitoring his temperature, make sure dia minum enough (breastfeed or bottle regularly) and observe for any breathing issues or lethargy. If demam naik balik atau dia jadi lethargic or susah nak makan, terus panggil doctor again jangan delay, better safe than sorry.
