“Swaddling has been shown to reduce crying and improve sleep. It is important to swaddle in a way that allows the baby to move its legs and hips. Colic is defined as excessive crying. It is self-limiting, meaning it will stop eventually. Changing formula or maternal diet, treatment with a probiotic, or both have shown some positive impacts. Collecting data on your baby is fun! But not necessary or especially useful. Exposing your infant to germs early on risks their getting sick, and the interventions for a feverish infant are aggressive and typically include a spinal tap. Limiting germ exposure may be a good idea, even if just to avoid these interventions.”
