i had the same problem with my son going to preschool. it didnt take as long as my daughter with daycare though. my son was in daycare at 1 month. i cried for 2 weeks when he would go to school because he cried when i left him, he didnt at day care but did at school. i took a picture of me and his dad and gave it to him to take with him. it worked and eventually he made other friends at school and forgot about the picture. i would sit down and talk with him about y he didnt like it if he didnt want to go and we sorted things out. i still do that with him and he's in 1st grade. my daughter on the other hand i had a different situation..she always had dad watch her and when it came time to go to day care at 3 yrs old it wasnt working, what did work was switching her daycare (we discovered some problems at the first one that didnt work out)and one of the women that work there sat with her and talked with her(pretty much made her feel comfortable), and she made sure she was there when my daughter got there. she did that every day for prob about a month and eventually my daughter went off on her own and now runs into day care(she's 4) every day. sometimes kids just need someone to feel "close" to when we're not there, maybe her teacher could spend some time with her or something so that she doesnt feel "lonely". it will work out, it just takes time.
