Aww mama, yan ang nakakaalala talaga! A few of us moms nag-experience din ng ganyan after baby had fever, parang nafflect sa feeding habits nila for a few days, so it's not unusual. Since your pedia said babalik to normal and baby's already eating lugaw and soft food okay naman, baka it's just the fever that threw off her routine, or she's maybe exploring new tastes na, kaya mas preferred ang solid foods ngayon. The biting though could be discomfort from her mouth or just testing boundaries, pero since nangyari after the fever, I'd say give it maybe another week or two before you worry, often they bounce back once they feel 100% better. Keep offering the breast kahit may rejection para hindi completely mawean, at check with your pedia ulit if it doesn't improve soon or kung may other signs na off. Mama, you're doing great monitoring this closely!
