It’s probably one of the biggest fears of soon-to-be parents. Colic is a condition described as excessive, persistent crying in seemingly healthy babies that lasts for more than 3 hours a day, 3 days a week, for 3 weeks. It can effect around 20% of babies and is one of the more stressful things a new parent can go through. Generally its effects are more prevalent between months 1 and 4, after which the length of crying trends less and less until eventually stopping.
