Hi, I am new to this site and this is my first post. I am a first time mom and have a happy 7 month old son.. Lately he has been screaming and I mean it is high pitch, blood curdling, hair stands on ends screams and he often smiles when screaming. He has a little walker that he uses and seems to do most of the screaming while walking around in it and once I or my husband looks at him, he smiles and then stops just to start up again once we look away. The screaming is horrible and I am not sure what to do about it if I should even do anything. He obviously won't understand that he is being loud or hurting our ears and it's not a fussy kind of scream at all... he seems happy when he screams and squeals. Is anyone else going through this or has anyone gone through this? I don't know what to do and I only have so much tylenol to take for the headaches. Any advice??
