Why is it that when I'm nursing one twin, if the second twin starts to cry that I start rocking the first twin over and over? It's not like the first twin is upset. Heck, they've got the boob! They're happy!
Then, as the cries get worse, the rocking gets faster and faster. Clearly my subconscious is expecting calming waves are transmissible via twin to twin brainwave.
So far? No such luck.
Updated to add: I forgot to mention that this usually happens when I'm trapped in the car in a parking lot somewhere.
