My 9-month-old still wants to nurse every three hours at night. how can i successfully stop this?

Feed as baby wakes: If your baby has paired feeding with settling to sleep, you need to rework the pattern. Get baby to feed as s/he wakes , followed by body maintenance, playtime & put down when tired to sleep without re-feeding( even if fussy). Allow no more than 2 hours for day naps before waking at the breast and continue the pattern. At night, feed as baby wakes, change & put down still awake. Sit close if needed.
