Hi ladies- my daughter is 16 weeks old and normally is a great sleeper (10-12 hours at night), usually falls asleep on her own, and is a happy baby. Since last week she is waking up at night, crying/screaming until she’s picked up during the day and someone’s that doesn’t work, needs to be rocked intensely to go to sleep, refuses to nap, and is guzzling down 5oz almost every 2 hours. I’m really struggling and wondering if anyone has any tips/suggestions? I also took her to the pediatrician to rule out any illness and he said “a sick baby does not gain 15oz in 19 days-she is fine” 🙄😂
