1st week at child care

Sent my boy to childcare when he turned 2. Boy oh boy, first week was terrible. Cried and cried, both in school and at home in the night. Saw his uniform and started crying in the morning. It's a full day CC, but for the first week teacher advised us to send him 9am to 12pm. 2nd still couldnt start full day CC, but at least the crying got lesser. By third week he walked him on his own and said bye bye to us at the door . Now it's been 10 months, sometimes he just walks in with no byebye 🤦🏻‍♀️
