Yep, us too. Again, very bright well spoken chickie who had never a care going off to daycare, has started screaming in the last 6ish months.
Iberru has given some great advice.
I've never been one to force situations either and fund that she will get her confidence back at her own pace.
Throughout the day I always tell her where I'm going (to the loo/clotheslines/letterbox etc) and ask if she's right or does she want to come. Also I never leave when she isn't looking and I always tell her when I will be back.
mate. It does pass.
