A conversation on another board has brought up the possibility of only one parent being "Team green" and that it's possible for the parent that wants to know the sex to indeed know it, plan a nursery, and just not share the sex with the other parent.. along with the other parent just not entering the nursery if they don't want to know.
I find this highly unlikely to work AND considering it's mom that doesn't want to know, can cause some major riffs about not being able to be part of the nursery design, etc.
What do you ladies think, can you be half team green?
ETA: Dad wants to know so he can plan, so him knowing WOULD likely entail nursery planning. This is the part that is getting me on how it could, likely wouldn't, work.
