7 week old baby not sleeping well

If you are okay with yaolan (cradle swing), can try that. My mil used that for my LO on and off until she’s 2 months old. (She can sleep 3-4 hours with yaolan) Your baby probably needs to sleep more in the daytime as well at 7weeks. Also, is baby drinking well?

Same with my baby.. 7 weeks now also. Bought the Yaolan last week and it worked wonders
