Girls, we've noticed that the baby has been moving strangely for 1.5 months. Yesterday, I noticed that the child moves without stopping, always in the same direction, especially towards the head. It jerks sharply and suddenly. It strains when I lift it up and tilt its head back. He became restless, his hands and feet twitching because of this, he can't sleep. If you cover him, he tries to pull his hand out and cries. If he falls asleep, he suddenly twitches and wakes up. Today, we went to see a neurologist, they referred us to an ultrasound technician. They said the baby has post-hypoxic changes in the brain. Has anyone had this and how was it treated
