So my son is almost a month old, but for the past few days if I'm not holding him he screams bloody murder. He's constantly feeding all day and night. And if he loses the latch he also screams. It's been 3 days since this started. I don't think it helps that he was also just circumcised. I'm exhausted. I use a pacifier when I can but he also will knock it out repeatedly and again screams. Is this normal? Is it almost over?
