There sure were a lot of answers that do not fit. Test for pain by distracting him like picking him up and talking to him, and if he stops, he is fine. He is in a world of discovery and he is seeing what others will do. Laugh with him and make over him so he notices and then let him stretch his chords. He could be a future rock star. 5months is a sweet age where they demand a little more time from you and can become afraid of strangers and be really happy with siblings and he invites them into his little world. Have fun.
Well, i have a niece & she repeats everything she hear so probably your son heard that word from somewhere & decided weather hes in pain or not but you should just cheeck him if their is somethinq wrong with him
some kids just scream alot and others don't...apparently i was a screamer when i was a baby but grew out of it pretty quickly so he's probably going through a stage but be sure to check him out...diapers,,,when he was fed last, any rashes or wierd marks
He's just being a kid!! My daughter is 4 (going on 5) and she still does it every once in awhile now. 1-3 years old she would do it ALL the time, I think they like to hear themselves too. Just ignore it- if you make a big deal about him screaming he'll keep doing it.
My son screamed all the time until he was about two. Doctors wouldn't believe me and just told me all babies cry, but this wasn't a cry it was screaming. Everyone told me that they had never heard a baby scream like that, one doctor finally heard it but didn't seem concerned. He did eventually grow out of it. Mostly. But it was terrible. Check with a doctor to make sure there isn't anything serious but it's probably just the way he is right now.
