Child Parent AHHHHHH

Hey there guys,
addChild is handy in a lot of ways but has (for me) made some of the simple things harder.
My problem is loading a movieclip in a container and then replacing it with another.
in as2 you would just attachMovieClip on the container and it replaces the last clip.
If i do it in as3 it just adds it to the stack is there an easy way round this anyone that i am missing? so i can easily load a clip and remove whatever is in the container.

Cheers for your help…:slight_smile:
