My dau is 10 weeks old. She screams and screams. Is it that she wants attention? Please advice. When I carry her she keeps quiet and smiling always.

Mine also start the screaming affair after his 9 months old. He is going 10 months soon. He wants attention indeed cause usually he scares when he is being left alone for awhile and when he is excited or otherwise when my family members came home. Really scream like nobody business. Even when outside at times during the public transport rides, usually I give him snacks to stop his screaming a.
