My baby is 8+4 weeks old, and her nighttime sleeping has suddenly gotten worse. Last week she’d started sleeping stretches of 4-5 hours (which was an absolute godsend!) but as of Monday she’s back to eating every 3 hours throughout the night (she is exclusively breastfed). We haven’t changed anything about her routine so I have no idea why this has happened. Anyone else experience this around 8 weeks?! Any tips?
