It's easy to make mistake at this age of newborn baby about sleep.: Encouraging poor bedtime associations that require parental presence to put baby to sleep. Teach your child to soothe herself to sleep by helping her with a regular sleep routine.

Baby can start self-soothing, so if you haven’t started already, it’s time to establish a bedtime routine that you will practice every night. “A regular bedtime routine is very important because of brain development,” Waldburger says. “At this age, your baby can learn sleep cues.” A simple routine such as a feeding followed by a story and dim lights can signal it’s time for bed. A predictable routine will also make it easier for someone other than mom to put baby to bed.
 
It’s crucial to put your baby to bed awake starting at four months. Once your baby is able to soothe herself to sleep, she will be better able to go back to sleep on her own when she wakes at night. “If your baby gets used to falling asleep in your arms or with the TV on in the background, she won’t be able to recreate these sleep associations when she wakes in the middle of the night,” Waldburger says.
