Test yourself! Which boy is which? See if you can guess which one-month old is Holden and which is Milo without looking through the gallery. And don’t worry if you can’t guess. Some very close relatives have already been stumped by this test. And the only one who got it right had some extra help!

Results will be posted in a week. Guesses should be left as comments. Good luck.
