I want to keep name a secret but...?

Co

A part of me wants to keep our sons first name a secret (I don’t really have a reason too) and another part of me wants to share. I’m leaning towards sharing because four babies, including mine are coming into my family this December 18 through April 19!!! So I want dibs on our name. If all goes well our son is the second of the four. If we change our minds about his name (we’re 15 weeks) then OK. But if we don’t, I don’t want it taken from us! I love this name way too much!!! Advice?
