My baby will be 7 weeks on New Year’s Day. For the last three nights she won’t barely sleep longer than an hour. She normally sleeps about 3-4 hours at a time and it only takes us a couple tries to get her to fall asleep. The last couple nights it’s taken us almost 3hours to get her to fall asleep. She’s really fussy and seems to eat smaller portions more often. I’m not sure what’s going on all of a sudden. Any tips?! Anyone been through this before? Thanks 🙏.
