Praise be to Allah.
If you entered ihraam for your daughter then she did not complete it, you do not have to do anything, because ihraam of a child is not binding, as the child is not accountable. This is the view of the Hanafis and was favoured by some of the scholars.
As for the stipulation, it applies if there occurs any obstacle that prevents one from continuing, such as sickness, but fear of sickness or exhaustion is not sufficient.
And Allaah knows best.
