Girls, hello ? I'm having a panic attack eat me?. My son is holding his head unsteadily vertically. He holds it and twists in different directions with a toy, but doesn't lift his forearms. We can't get to a pediatrician or neurologist right now. We'll only be able to go after the 2nd. Tell me how you handle this? I don't even remember how it was with older children, but now I've started sleeping badly because of this panic. I've also read so much on the internet?
