Registry questions: Helppp!... FTM

Bryant

How many registrys are you supposed to have? Can you just do one.

If you have multiple, do you put the same stuff twice? ( I don't want to be opening same gifts)

Would it be easier just to have one, i was going to do buybuybaby and target but buybuybaby has more of the stuff we need and i want to make sure get what we really want; target doesn't have as much and what they do we have at buybuybaby ....

Idk what to do... I'm an over thinker -.-
