I have a 2 year old that started almost a year ago at the age of 14 months. She cried almost all the time for 2 weeks. She would go home with a hoarse voice. At the end of 2 weeks, one day I noticed it wasn't as bad as it had been. I had a discussion with her mom that if the not adjusting to daycare continued, I would let her go. After that day things gradually got better. There have been a few bad days but in general she has adapted and is quite the sweet little girl. If things didn't improve though I would have had to let her go.
