# Objective - Makes naming between add_child and add_children more consistent - Fixes #15101 ## Solution renamed push_children to add_children ## Testing - Did you test these changes? If so, how? Ran tests + grep search for any instance of `push_child` - Are there any parts that need more testing? - How can other people (reviewers) test your changes? Is there anything specific they need to know? - If relevant, what platforms did you test these changes on, and are there any important ones you can't test? ran tests on WSL2 --- ## Migration Guide > This section is optional. If there are no breaking changes, you can delete this section. - If this PR is a breaking change (relative to the last release of Bevy), describe how a user might need to migrate their code to support these changes rename any use of `push_children()` to the updated `add_children()`
