My son just turned 6mo. He is moving his head from side to side more frequent than usual. He's also pretty grunty and rowdy if that makes any sense. He responds well to his name and very active with his surroundings, toys, etc. he's social and smiles at everyone. Very happy baby. Still does not sleep well at all. Is there anyone who has similarities. I'm a FTM and kind of freaking out when I think about. Is this a call to the dr kind of thing?
