There's this hilarious hah hah how did humans survive this long things babies do where, when they are on your shoulder and find themselves hungry, they lurch to the side to try to get horizontal and lined up with a boob. And lurch. And lurch again. In practice, and since I have no boobs to offer, it ends up looking like an attempted dive of doom as the kid struggles to take its life in an amazing feat of lemmingry.
