I apologize -- judging by the downvotes my comment came across as really judgmental. The new parent exhaustion + the "confused newborn" expressions combined in a way that struck me as funny in a "these people all have silly expressions," way, not a, "haha those people are idiots" way. Like I wrote, I would not assume anything "real" about the intelligence of anyone in the picture based on this one snapshot moment. It really is a sweet family portrait, and I'm sorry for being a dick about it.

I'm not making a serious judgment based on a quick snapshot, but this picture makes it look like the combined family IQ scores wouldn't break 100
