“Does teething make babies sleep more?”

Teething can be stressful on an infant's body, which can result in increasing sleep. Teething can be painful, which can disturb sleep and result in fussiness and fits of crying. Fever is not uncommon, as is diarrhea, a diaper rash, and pulling on the ears. Only physical examination by a pediatrician can distinguish "teething syndrome" from a bacterial ear infection or other acute illness.
