Your child need your support until the age of majority. Since he can not make his own decisions and is not allowed too, you are the legal representative of your child.
Already in kindergarten, your child needs your support. Kindergartens regularly invite parents to exchange and share information about groups of children and their own children. You should regularly attend these meetings!
Even at school, your child needs your support. You should help your child with homework and communicate with the main teacher in case of problems to avoid problems and to promote progress in school. Here too, there are regular parenting evenings, which you absolutely must attend.
