I wonder if a newborn can recognize his/her own cry.
Yesterday I did a little "experiment" with my four weeks old daughter:
I recorded her cry for a while. Once she was relaxed again, I reproduced it next to her so she could hear it. I did this a couple of times on different moments. Surprisingly, in most of the cases she started to feel a bit anxious and, eventually, started crying again. Stopping the audio relaxed her again within seconds.
So I wonder: why did this happen? Is the recognizing her own cry or is the sound itself that alters her?
