My son is 8 months, he left the tumb sucking habit 4 the past 3 weeks.now he wants to be nursing while sleeping.only then he sleeps.is it bad habit?

Bad habit: No child should be put to bed with milk from breast or bottle on their newly erupted baby teeth. Teeth should be cleaned before bed. Talk to your Pediatrician now, and at 1st b'day make appointment wit a Pediatric Dental Specialist for exam, dental &.skeletal growth assessment, Fluoride management, oral hygiene program, and so much more.

Learned behaviors: start at 6 mos.,so he is "trained night feeder." At a consistent bedtime, read, cuddle, feed, wipe out his mouth with a soft cloth/ use an infant toothbrush, then put him in his bed in his own room drowsy, but awake, to learn to self-calm for sleep. If you consistently ignore night crying, it will first worsen, then stop. If you can't do this, HealthyChildren.org has a " graded ignoring" method.
