All newborns cry and get fussy sometimes. It's normal for a baby to cry for 2–3 hours a day for the first 6 weeks. During the first 3 months of life, they cry more than at any other time. New parents often are low on sleep and getting used to life with their little one.
You start with letting your little one cry for just a few minutes before briefly checking on them. As the night goes on, you gradually increase those response times until your baby falls asleep independently. Your baby's intervals of crying should be no longer than 10 minutes.
