Daughter crying every morning at drop off.

[MariaMcGrath87]

My daughter has started crying every morning at nusery drop off. She did a surestart programme last year where she stayed on her own 3 days a week and settled great, never cried. She didn't even cry her first day of school in September but since Christmas break she is really teary going in every morning. I've questioned her and there's no issues with school. She has lots of frinds and seems happy once she's in there its just the initial drop off. Any tips would be greatly appreciated because it's upsetting me just as much as it's upsetting her.
