Baby is 9wks old. She goes longer than normal without eating.

She gets really fuzzy and I know she’s hungry but she just won’t latch, it’s been going on for like 3 days, only difference is today she started doing that since early but I blame that with getting her ears pierced last night. The other 2 days she was only doing that after 6ish... I started giving her a pacifier around 3 days ago. Could that be affecting her latch???

my husband did have a cold and was complaining about his throat a lot (kept his distance from baby). Could she be sick? (No fever), what do I do? It’s been 5 hours since her last feed.
