Well our new house has 4 bedrooms , is it weird to have a nursing room and a bedroom for the baby. ?

Not weird but kind of unnecessary you can set up a nice rocking chair in baby bedroom and nurse there and use that room for something else but that's completely your choice 😊

Completely up to you but I see no need for a nursing room.

If I had a house that big ? You bet girl!

I'd do it in a heart beat!

i mean well you can make it into a play room whdn its ocer
