Screaming 6 month old

Rachel

My LO turned 6 months on the 10th. Since this Sunday he has been SCREAMING. He doesn’t cry or have any tears. It’s pure screams through the entire house, all day. As soon as he wakes up and after his naps he’s just screaming. I put him in the play pen, give him toys, even after his feedings. It’s like he’s restless all the time. But he takes all his naps and sleeps really well. Im losing my mind :(. I’m with him all day by myself. Hubby works 7 days a week and by the time he gets home LO sees him for 30 min and then He’s off to bed for the night. Please someone tell me what to do. I haven’t sat in silence in so long. My head is throbbing. I just hear screeching all day. He has never been like this.
