One thing I don't get is that the ingredients weren't destroyed or seemingly harmed in anyway when the spell was cast (yes, I know killing a baby on-screen would be a bit much). Doesn't that mean Rumple (assuming he learnt the spell during his time with Zelena), with the consent of Regina and the Charmings, can repeatedly use the time-travel spell to "fix" stuff?

So for example, Rumple can travel back to a few minutes before Hook and Emma were dragged into the portal, then stop them from going near it - problem solved.

And if any future villain were to appear, Rumple just needs to travel back in time a bit to warn himself and the Charmings so they can prepare and thwart whatever actions the enemy plans to take.
