My daughter is 4 months old and recently she has been crying or whining in her sleep ! She will randomly just start crying ! It's driving me crazy as to why she is doing this all of a sudden
my nephew did that when he was 4 months also. it was so bad. it lasted until 5.5 months. but it went away by itself. literally nothing you can do to stop it. its so hard to hear a baby cry in their sleep 🙁
