You know the scenario: someone asks if baby is sleeping through the night and you grimace and confess that they are still waking up and feeding/crying/playing. Cue sympathetic smile and reams of advice: let them cry, move them into their own room, feed them rice, don’t feed them, give them formula, give them different formula… until you run away or bean them with a large brick.
What to do? In most cases, lie. Oooh, she’s sleeping very well, thank you. We’re happy (of course we aren’t, but lie lie lie). He’ll sort it out eventually (highly unlikely IMO). Lie lie and lie again, then scarper.
