To be clear, they don't eat/feed at night either. The baby is in a separate room from us and we don't see or hear him most nights (95%+) between 7pm-6am. He's around 8.5 months old now and this has been the case for 3-4 months, although that percentage was a bit lower at the beginning.

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.
