my son has just turned 1, and ever since he was a few months old he's cried when other babies cry or scream. He doesn't usually cry at loud noises like sirens or anything like that. But when my partners little brother comes round, as soon as he cries or screams my LO burst into tears, I mean he gets quite hysterical. Today I was in the doctors and there was a girl around the same as my son and she was making a funny noise (she wasn't being loud or crying) and he burst into tears again. I also have a toy that makes a moo noise and he cries at that as well. Has anyone else experienced this with their LO? I'm so worried!
