Colic
The dreaded colic cry is intense, and mimics more of a constant scream, with jerk motions.
What to Expect reported:
“Colic often occurs in the late afternoon or evening, and the episodes can last for hours. It typically starts at around 3 weeks after birth and goes away by the time baby is 3 to 4 months old.”
Do your best to comfort them while they get through this tough period. Try laying them on their belly across your forearm or knees.
It is also important to note that food allergies or sensitivities can mimic colic. The most common of these are dairy, gluten and msg. Talk to your pediatricians if you have concerns.
