Oh, today is my boy’s first day at preschool, he cried like crazy and after i left he even threw out. He didn’t want me to leave at all. I was very upset and even depressed for a while. I know there is separation anxiety, how can I ensure him that i didn’t abandon him? He is growing up and needs to go to preschool. He is very happy when we were together at home, going to different places. But mom is drained up, baby, mom needs to do her own things and makes a living, to earn money that can buy toys for you. Baby, please adjust and adapt to your new life quickly and happily.
