Timetable for the child(ren)
The timetable for the child will be set by the court to take account of dates of the *significant steps in the child’s life that are likely to take place during the proceedings.
Those steps include not only legal steps, but also social, care, health, education and developmental steps and any timetable for a case with an international element.

significant steps - важные этапы или важные меры? (с учетом legal steps и т. д.)

Спасибо.

в ходе proceedings, скорее, речь о мерах/шагах/т.п., которые take place - этапы здесь не монтируются)))

(1) any formal review by the Local Authority of the case of a looked after child;
(2) any significant educational steps, including the child taking up a place at a new school and, where applicable, any review by the Local Authority of a statement of the child’s special educational needs;
(3) any health care steps, including assessment by a paediatrician or other specialist;
(4) any review of Local Authority plans for the child, including any plans for permanence through adoption, Special Guardianship or placement with parents or relatives;
(5) any change or proposed change of the child’s placement; or
(6) any significant change in the child’s social or family circumstances.

" health care steps, including assessment by a paediatrician " - явно не этапы, а действия/меры и т.п.
