The first night was very hard as he kept crying for his mum. I was so annoyed and then went out of the room, telling him: all right, please cry.
He was so scared for staying in the room alone, so Lele ran to me and said, don't leave, don't leave.
Ok, I said, listen, now you have two options:
CRY, or SLEEP, which one you want?
he said, sleep.
So we went back to the bed and he got into sleep in one min!
From then he is more and more independent.
