One day, your precious baby may appear to suddenly turn on you, unexpectedly pinching your skin or yanking your hair. (Ouch!) Don’t freak out! Your little one has not morphed into a tiny bully. It's quite common for babies to poke, pinch, pull, and even bite the grownups they love the most. Like so many things with kiddos, this is just a stage. Here’s how to get through it (almost) unscathed.

Why is my baby hurting me?

Chances are, your little one’s “aggressive” behaviors began somewhere between the ages of 6 and 12 months old. This is prime time for your baby’s explorer tendencies to explode. They’re very busy getting to know the world around them, examining the way things taste and feel...and the brand-new concept of cause and effect. (If I pull this, Mama does that!) Adding to the excitement: You little one’s fine motor skills are really starting to come together around 9 months, as they start to master what’s called the pincer grasp. This is when babies can use their thumb and forefinger together to grasp your hair and skin. But truly, your baby is not trying to hurt you! They simply put these behaviors on repeat because that’s how they learn. It’s up to you to gently redirect these actions. If you don’t then pinching during breastfeeding, for example, will become a habit. That said, biting while breastfeeding could mean something else is going on.

Why is my baby biting while breastfeeding?

In addition to the above explanations, your little one may be using their teeth on you due to…

  • Teething: Starting as young as 4 months old, teething babies may bite down to soothe their sore and swollen gums. Try offering a cool teething toy or frozen washcloth instead of your breast.
  • Stuffy nose: It can be hard for congested babies to breastfeed. Reposition your bug to be more upright, allowing for an easier feed. (More ways to safely treat a baby's cold.)
  • Ear infection: Here, the act of sucking may hurt, so your baby is letting you know: No more! (If your baby is also tugging at their ear, this is most likely the issue.)
  • Distraction: This mostly occurs at the tail-end of a feed when your baby is getting bored, not paying attention, and frankly, isn’t very hungry anymore.
  • Milk flow issues: Your baby can’t bite if they’re actively sucking, so your little one may be trying to get more milk to flow. To help, give a quick breast compression to up the flow, which’ll prompt your baby to suck and swallow.

How to stop baby from biting, pinching, pulling-hair, and more:

Whether your nugget has taken to pulling your hair, pinching your arm, or biting your breast, the make-it-stop principles remain the same. Here they are:

  • Stay calm: Little ones are exploring the notion of cause and effect, so if you offer up a big reaction, you may inadvertently be inviting them to try again to see what effect they can cause next!
  • Halt the habit: If you’re getting pinched or pulled, gently remove your baby’s hand. With biting, follow the advice above and try placing two fingers in their mouth to separate their jaw, and pull them away. As you do, firmly say, “ That hurts.”
  • Redirect: For example, if your tyke gives your hair a yank, gently remove their hand and show them a nicer way to touch your locks. You can also lightly stroke your baby’s hair, while softly saying
  • Offer a cold shoulder. If the gentle removal, No, and redirect weren’t enough, turn away or put your baby down...calmly. (Learn more about using Kind Ignoring to stop bad behavior.)
  • Remove opportunities. Put long hair in a ponytail, remove dangly earrings, and otherwise try to eliminate other temptations for your newly combative least for a bit. With that, know that biting while breastfeeding is not a sign that your baby is ready to wean. Instead of taking away your breasts, follow the advice outlined above. 

When biting, biting, pinching, and hair-pulling is something else:

Hitting, kicking, biting, pulling tends to peak between the ages of 18 months and 2.5 years old when kiddos are bursting with emotions, but their communication skills haven’t caught up. Remember, toddlers aren’t mini-adults (or even mini-big kids) ...they’re more like uncivilized little cave-kids! So, it’s no wonder that these little tykes have days when their impulsive, primitive nature takes control and makes them do things they shouldn’t. If you’ve got a toddler who’s demonstrating some aggressive behaviors, it’s important to act swiftly...but gently. Here’s how to expertly stop these types of toddler And here’s even more help on dialing back a toddler’s biting behavior.
