This error occurs because you instantiated the Child class with the new operator.
In FLOW3 you must (almost) always use the object manager for creating instances
(see below).

However, a more friendly error message would be nice - therefore, would you
please open an issue in the FLOW3 project so we don't forget to add an addtional
check?

Try this:

$this->parentRepository->add($newParent);
$newChild =  $this->objectManager->create('F3\MyPackage\Domain\Model\Child');
$newParent->addChild($newChild);

you don't need to add the child to the ChildRepository explicitly because it's
already connected via the parent.

Cheers,
Robert
