I'm expecting about 75-100 people at my baby shower :/ we have to rent out a place it's crazy .. Anywho I really don't wanna open ALL OF THOSE gifts but I can see how people may feel it's rude or ungrateful.
So I came up with two ideas:
Opening gifts as the people walk in
Opening gifts table by table...
How about a gift opening time where everyone picks a gift and then sits back down, then each individual gets to unwrap the gift and pass it around the circle, make sure names are added to each gift when unwrapping the item.
