Demon goo turns Buffy and Spike into children

It is set in either season 4 or 5. Buffy and Spike are out slaying and a demon explodes on them. They go back to Buffy's to shower off the goo. In the morning Buffy wakes up to find Spike as a little child. She takes him to Giles. The next day she wakes up as a child too. Angel shows up to help and actually removes Spike's chip when he gets hurt.

I think this is it.
