Dh finally got it out of her, and my DD (2.5 years) said she is lonely at school (daycare)

DD has been having a hard time at daycare. She goes 2 days a week (Mondays and Wednesdays) and cries every time she has to go. Every morning she wakes up at 5am and asks if today is Nanny day or is she going to school. If we say school she cries. She tells the teachers she misses me and I found out today she said she was worried about me. DH finally got it out of her and she says she doesnt have friends and is lonely. One of the teachers (not A's teacher) said she usually clings to the teachers when they come and she does not really interacts with the other children. DD has lot of cousins around her age and plays with children nicely at the pool and park.

What can I do to help her make friends so she is not so sad?
