Your baby can begin teething any time between 3 and 12 months. Your baby will be in a lot of pain – I mean, a tooth is cutting through their tiny little gums – so the signs can range anywhere from drooling, coughing and crying to diarhoea and rashes across their chin and face. Most paediatricians agree that a baby won't get fever from teething, so if you're baby is sick, first take her to the doctor.
