litter rabbit,
If ur bb is not in distress (i.e. crying), then more likely he is just being excited and experimenting with his voice (& volume). At this stage, most bbs are getting fascinated with the sounds they can make so its pretty normal.. my bb does the same thing and then laughs as well. At times she will quieten down when i start talking to her in a quiet and low tone face to face. Bbs also enjoy looking at faces so having face to face contact may help to distract ur bb from the 'screaming'.
