Interacting with objects in the scene

I am working on an animation that involves picking up things. I have a character that walks to the object and reaches out for it. My problem is that i want to parent the object to one of the bones in the character. When i do this however it is parented from frame 1 and i only want it to be parented from like frame 400 onward. Any help would be much appreciated.

Don’t parent it. Use a copy location constraint and constrain it to a bone in the hand. You may need add a bone to constrain it to. Set the influence to zero at first, then jump it up to 1 on the frame where the object gets picked up.

Ok, thank you very much.
