Re-fetching resolved data for child component

Question

I have a parent component that loads child components conditionally. One of them being:

<ng-container *ngIf="someCondition">
    <app-some-child></app-some-child>
</ng-container>

There are no child routes for the parent component. The route has a resolver to which app-some-child subscribes to:

this._activatedRoute.data.subscribe(({ clientData }) => {
  // Client data came from a server
});

The child component app-some-child is used to create the client data:

this.clientService.create(client).subscribe(res => {
  // Client created
});

The problem

When I navigate back and forth between child components, the resolver is obviously "not designed" to be called again in this way. So, after creating a client, what is the best approach to use in order to keep the client data when initializing app-some-child again but still using the resolver?

"Dirty" solutions:

1. I could re-subscribe to getting the client from server on app-child-component but then I'm dealing with duplicate subscriptions.
2. I can use a singleton to keep the client in memory after creating it and subscribe to it.
