Sorry, Cally. It is tough, isn't it?
My DD is in care 2 days/week. Started in July (she was around 18 months old) and as of about a month ago she doesn't cry anymore when we drop her off. And some weeks she will lead us in by the hand and wander off and play of her own accord.
Hang in there. I never thought I'd see this day, but here we are
