My LO is 3 weeks old. I was told to feed every 2-3hours. But if baby sleep more then 3hours will you wake them up for feed or let them sleep till they cry for milk ?

If baby is clear from jaundice you can let lo sleep longer . But if you want them to sleep at night you might want to wake lo up as so that they can recognice between night and daytime.. If you direct latching ,just feed on demand , not by schelduling . Wait for baby cues.. Cheers to us mommy !!
