Finally the last 2 days of the first week. Having the experience of mummy leaving the classroom without him, On the 3rd day, Izaac cried and quickly held on to me when it was about to go home. I had to assure him that I will be waiting outside the classroom for him.
On the 4th day, I decided not to go into the classroom with him and he cried from the moment he stepped into the classroom. Can see that he was unsure of what to do and he was insecure with the whole environment. As we could peeped through a tiny slid through the window, I stood there watching him standing there helplessly then after awhile heard him telling the teacher that he wanted his mummy.
