Ok for the second night in a row my baby is just upset and crys and nothing helps but nursing her. She has been fine in the morning it's not till later around 4 that she starts just screaming. but then she sleeps pretty well on and off through the night without screaming. Idk what to do I haven't been able to make dinner and having a hard time taking care of my toddler when I can't put her down. Help lol
