Stay calm, get the details from the teacher and agree on one plan for home and child care. Biting and hitting usually peak around age 2, and most kids outgrow them as their words and self-control catch up.

Why do toddlers bite and hit?

Big feelings, few words. When another kid grabs the toy, a bite gets fast results, and the toddler learns it works.

Self-control is still under construction, so a child who can recite the rule may still break it in the moment. ZERO TO THREE points to teething and not having words for frustration as common reasons. Here’s its age-by-age breakdown:

AgeWhat’s usually going on
Birth to 12 monthsBabies explore with their mouths and hands. Biting, grabbing and swatting aren’t meant to hurt.
12 to 24 monthsFeelings are strong, but words and impulse control are limited. Aggression often peaks around age 2.
24 to 36 monthsAggression often follows overwhelming feelings, such as anger, jealousy or missing a parent.

Group care adds its own triggers: drop-off, cleanup and other transitions, crowded play areas and being tired or hungry. A new baby, a move or a switch to a new classroom can play a part too. Some kids bite for the sensory input. If mornings are the flashpoint, here’s how to make daycare drop-off easier.

What Massachusetts rules require

Programs licensed by the Department of Early Education and Care (EEC) must guide behavior in positive ways, like reinforcing good behavior, setting clear limits and redirecting. They can’t spank, humiliate, threaten, or withhold food or outdoor time as punishment.

A time-out can’t last more than one minute per year of age, and the child must stay in an educator’s view.

Injuries? The program must tell you right away about an injury that needs more than minor first aid, tell you by the end of the day about minor first aid, and give you written notice within 24 hours.

Group programs must also have written steps for avoiding suspension or expulsion over behavior: a meeting with parents, referrals for evaluation, outside support for staff and a behavior plan for home and program.

How to work with the teacher

  1. Get the details. When does it happen? Where? With which kids? What came right before?
  2. Share what’s new at home. A new sibling, a move, poor sleep or teething can all matter.
  3. Use the same words. If the classroom says “Gentle hands,” say it at home too.
  4. Check in often. Behavior can take several weeks to change after a new plan starts, so give it time before judging it.
  5. Ask for a written plan if it keeps happening, and ask who else could help, such as a consultant, Early Intervention or the school district.

What to do at home

What if my child is the one who got bitten?

When should I get more help?

Occasional hitting or biting is typical. The AAP and ZERO TO THREE flag these signs to raise with your pediatrician:

  • Aggression is unusually frequent for more than a few weeks, and home strategies aren’t working.
  • Your child bites several times a week.
  • Your child injures others or themselves, or attacks adults.
  • Your child is sent home or barred from play.
  • Hitting seems unprovoked, or started after a trauma or major change.
  • Your child craves intense sensory input in ways that hurt.

In Massachusetts, children from birth to 3 can be referred to Early Intervention (EI). Anyone can refer, and there are no out-of-pocket costs. From age 3, your public school district handles evaluations for early childhood special education at no cost.

For children who need extra support

Kids with speech delays, autism or sensory differences may bite or hit because it’s the fastest way to communicate. Ideas to bring to the teacher and your child’s therapists:

  • A quick way to say “Stop,” “Mine” or “Help”: a sign, a gesture or a picture card within reach.
  • A card or lanyard with faces for happy, sad, mad and frustrated, so your child can point to a feeling.
  • For kids who seek oral input, safe chewable items and sensory bins.
  • A calm space and warnings before transitions.
  • If your child has an Individualized Family Service Plan (IFSP) or an Individualized Education Program (IEP), ask the team to share strategies with the classroom. In Massachusetts, early childhood special education can be delivered in a child care setting when the IEP team decides that’s right.

Common questions

Is biting at daycare normal?

For toddlers, yes. Biting and hitting usually peak around age 2, when feelings are big and words are few. It’s a concern when it happens several times a week or keeps going for weeks despite a plan.

Can my child be kicked out of daycare for biting?

Massachusetts group programs must first follow written steps to avoid suspension or expulsion, including a meeting with parents and referrals for help. Before suspending or ending care, a licensed program must give you the reasons in writing, plus any conditions for return. Ask to see the behavior policy.

Should I bite my child back so they know how it feels?

No. Biting or hitting a child teaches that hurting people solves problems. The AAP links physical punishment to more aggression, not less. Stay calm and teach a better way.

Will the program tell me who bit my child?

Ask how your program handles it. Whatever the policy, the useful conversation is what happened and the plan to stop it from happening again.
