I'm emphasizing it bc many people are surprised by this, but if you know it's possible, you can start to work towards it. My partner's coworker has a ~1 year old who was still waking up (maybe multiple times?) each night to eat. She introduced them to one of those books (the 12-by-12 one) and they were very grateful.
Thanks for your recommendation anyway. I'm sure that there are many science-based techniques to "tame" children and make child care as atomic family bearable.
We didn't force anything or ignore him. And you don't have to believe me, but I'd encourage you to research more for yourself if waking up at night to feed a baby is something you're currently dealing with.
