Three girls who are seven, five and three years old neither made Sa`y nor performed Tawaf-ul-Ifadah
A 2: First:
You have to go back with those mentioned girls to perform Tawaf and Sa`y for them. It will be sufficient and would discharge the responsibility if you did not perform Tawaf-ul-Wada` and go home immediately after making Tawaf and Sa`y. You also have to
offer a Fidyah (ransom) for each one of them because they neglected throwing the pebbles, this Fidyah should be slaughtered in
Makkah, provided that it meets the same conditions of an Ud-hiyah (sacrificial animal offered by non-pilgrims) and its meat must be distributed among the poor of Al-Haram (the Sacred Mosque in Makkah).

Second:
You have to perform those rituals which have just been mentioned as perfectly as you can in accordance to what Allah (Glorified be He) says:
So keep your duty to Allâh and fear Him as much as you can
