Looking for advice. DS is 2 and a typical covid baby. He's started at a preschool one morning a week and that's going ok but otherwise I can't leave him and he goes bananas when I'm out of sight. I'd like to just be able to leave him for the odd hour here and there so I can run an errand. Any advice on how to help him with this? A lot of 'well-meaning' friends say he's just got to get over it etc but it's not that easy so I'm looking for advice from people who really get what it's like having a v clingy child. Tia
