Hello everyone! My son was an active, normal boy until this week. He threw toys around, curious, could break flowers, barked, cried. But for the past week he's been incredibly quiet and calm. Silent to the point of being scary. Toys aren't interesting, flowers too, even his little finger doesn't cry out, he just sits quietly and tries to pull himself out. The garland he used to look at with interest now just passes by. I used to get him all excited, he would scream and try to run away and we joked about fighting. Now he just sits silent and waits until I stop kissing and leaves. And I miss our battles so much ??? What could it be?
