Why Toddlers Bite and What to Do About It
By Maya Fairbrook · Oct 24, 2026 · 6 min read
In a nutshell
Biting is common between one and three. A calm, consistent response helps it pass faster.
Biting can be upsetting, especially if your child bites another child at nursery. But it is a normal phase for many toddlers, who have strong feelings and limited words to express them.
Understanding why your child bites makes it easier to respond.
Tip 1 Common reasons
- đź’ˇ Teething discomfort
- đź’ˇ Frustration or anger they cannot express in words
- đź’ˇ Excitement or overstimulation
- đź’ˇ Wanting attention
- đź’ˇ Exploring cause and effect
Tip 2 In the moment
Stay calm. Say firmly and simply, “No biting. Biting hurts.” Comfort the child who was bitten first, which also shows your child that biting does not get attention. Move your child away from the situation briefly if needed.
Tip 3 Prevention
Watch for patterns — tiredness, hunger, crowded play — and step in early. Teach simple words or signs for feelings like “mad” or “stop”. Offer teething toys if teeth are coming through.
Tip 4 When to get help
If biting continues past age three or four, is frequent and intense, or comes with other concerns about development or communication, talk to your health visitor, paediatrician, or child’s nursery for support.
This is general parenting information, not medical advice. Every child is different — talk to your paediatrician, family doctor, or a qualified specialist about your child’s health, development, or behaviour. In an emergency, call your local emergency number.
