(b) where such proceedings are dismissed after the beginning of the trial, either forthwith or within a reasonable period after the dismissal and in any case in which the Court has power by virtue of this subsection to make an order in respect of a child it may instead, if it thinks fit, direct that proper proceedings be taken for making the child a ward of Court.
