First day at nursery

Today is Edmund first day to nursery. I brought him over around 7:15am. The teacher there try to carry him from me, he keep saying don't want (in mandarin). I try to put him down, he cling to me like koala bear! Even I show him the toys there he also don't want. Then the Principal came and carry him from my hand. He start crying and call 'mummy, mummy'. The principal carry him to kitchen, where I hurried went out. I think not to let him saw me, he will be less fuss. But it such a heartache to see him crying like that.
I went to pick him around 11:45am, when he saw me, he is so happy. The principal told me that he stop crying when other children came and he play with them. But occasionally he will moodless, maybe he is thinking of me. He have one bowl porridge and a banana.
I sure tomorrow will be more difficult to left him at the nursery, :(
