Good morning, moms. My son is turning three soon. He's been screaming for a week now. Screaming straight out of his head. Crying, crying, nervous. We went to see a neurologist. They gave us a prescription, but it doesn't help. What should I do? What would you recommend? I'm so tired. He sleeps well at night. But when he wakes up... ??‍♀️ There's no peace. He needs to be sitting next to him all the time. I want to scream!
