Going to school

Next Monday I am going to enrol Joey to school (kindergarten) I was planning to enrol Jodel also but she is only 3 years old but I am not sure if she could go to school this year. She is going to be 4 on October and Jodel's doctor won't give her a shot until she turns to 4 years old. I am a little bit upset but that's okay. Well, I am hoping that she could go to school also this year.
