Most kids begin to teethe between 4 and 7 months. Teething can be very painful for some infants, while some might have irritability. Sometimes the baby feels discomfort as the tooth erupts through the gum’s surface.

Symptoms:

• Increased drooling
• Refusal of food
• Diarrhoea
• Bringing hands to the mouth
• Rejecting food
• Rubbing face
• Trying to bite, chew & suck everything
