Ivy has discovered that Noah has an added appendage...down below!

She was fixated on it all through bathtime and even had a tug or two (Noah didn't mind at all).
It was pretty funny and cute the way she looked at it and then looked down towards her own. I think the penny finally dropped that they are not the same human being, they are seperate entities!

My only worry is that it will become a habit and never having had a boy/girl pair I don't really know what to expect.
Anyone out there with a boy and a girl gone through something similar and how did you cope? Did they eventually grow out of 'inspecting' each other?
