My baby was never attached to me ever. Now he is 19 months and all of a sudden doesn't let me leave his sight for a minute. He screams bloody murder when I leave to the restroom and when I come back I see vomit everywhere. He will not even stay in the same room with his dad anymore unless dad holds him. I'm really confused to what caused him to become so clingy now. He's older and I though younger babies have separation anxiety which we never experienced when he was little.
