Why is my baby suddenly screaming?
If a baby starts crying hard or in an unfamiliar way, is suddenly very upset, or won’t settle at all, the baby may be in a medical crisis. If parents don’t see anything obviously wrong, they may want to quickly remove all the baby’s clothes and look for a pin sticking into the baby, a very hard tummy, a new rash, a fever, or anything else abnormal. Sometimes a hair or thread becomes wrapped around a small part of the baby and strangles the tissue. Any vomit or poop should be examined for blood.
