Anybody dealing with a clingy toddler? Si clings to me like it’s life or death. I can’t stand up without him crying. I don’t like to take him out in the cold as much when I go to the store so I’ll leave him with my dad or my best friend. He will scream bloody murder if I put my coat on and it’s getting pretty bad...any tips?
