Your baby is healthy, well-fed, and the diapers are freshly changed, in addition to being well-rested and getting plenty of cuddles and playtime. So why are they still crying? It is possible that your baby has colic. Essentially, it is a term that encompasses excessive crying in otherwise healthy babies. It typically starts around the 2-week mark and goes away on its own at the 4-month mark. It is frustrating for the mother or caregiver, as there is no inherent cause for colic. You know it is colic when the baby resists any form of soothing, and cries for at least 3 hours a day, 3 days a week, and has been doing so for the past 3 weeks. These fussy crying periods can go on till late at night, and is frustrating for everyone involved. A little knowledge and a lot of patience will help you deal with colic until it gradually subsides.
