@lalagata B,G,G over here and it’s great! Seeing my son really embrace the big brother role to his sisters is the sweetest thing, and I think it’s helped make him more sensitive and gentle already at a younger age. The girls also get along (for now) but we will see how that goes since we are only a year into it.
We didn’t care one way or the other which gender we had, so we were ready for anything. It’s worked out well.
Another logistical thing I love about it since we are done at 3, we now can get rid of all the overtly “boy” clothes (handsome dude, grandmas little guy, etc) to have the wardrobes already set in storage for the two younger girls when they get there.
