4 year old not in school yet

    My niece's little girl went to Jk the first day of school and
    maybe tried another day and then told her mother that
    she didn't want to go back. She told her mother to tell the
    teacher to take her name off the class list. When the child
    is asked about school she says she will go to school
    when she turns five. My niece has three older children
    who have always gone to school willingly. Do you think
    my neice has done the right thing to keep her youngest
    daughter at home for this year?
