A baby chewing and biting their crib rail can be disconcerting, particularly if parents are stressing about crib paint or crib damage. But parents who wake to find the crib railing peppered with tiny tooth marks should know it’s not necessarily a cause for concern. Babies use their mouths to analyze the world. It’s called the rooting reflex; anything that brushes against their cheek or lower lip gets a gum job. It’s a natural instinct that doesn’t really cause harm. There’s no reason to rush right out and buy a crib teething guard.
Melanie Potock is a pediatric speech pathologist, feeding specialist, and author who understands how and why babies investigate the world with their mouths – and how that exploration transforms into chewing through their bed rail like a cartoon woodchuck.
“Between the ages of 5 and 10 months, a baby’s front teeth are emerging on the bottom and top gums, and a baby is drawn to gnawing on almost anything,” explains Potock. “By a year of age, because of gnawing on food and other objects, kids can move their jaws in a diagonal motion when chewing food and wide up and down motions on hard surfaces, like the crib railing.”
For babies, chewing on a crib railings isn’t merely about discovery. It’s about pain relief. As any parent who has seen those swollen, sore-looking gums – and dealt with a cranky baby – can attest, the teething process HURTS. It’s not just the first round of teething, either – those toddler molars are hard to reach and can cause a lot of discomfort and frustration, and the process can go on for months.
An Award-Winning Formula
Looking for a formula you can trust to support your baby? Enspire is Enfamil’s closest formula to breast milk ever. It has Lactoferrin and MFGM which have been associated with fewer digestive and respiratory issues.
“Molars begin to erupt between 9 and 15 months, and then come the cuspids peeking out by 18 months of age,” explains Potock. “Those teeth continue to emerge over time and second molars erupt approximately around two years of age.”
So that biting serves to soothe babies and help those teeth cut through. But parents don’t have to resign themselves to two years of catching splinters and worrying about the ingredients in crib paint (although please check the annual recall report for peace of mind.) Parents can discourage inappropriate gnawing by protecting the crib itself as well as supplying the baby with the teethers they need to help relieve that discomfort and keep their minds stimulated and exploring.
Extra-large baby-safe silicon guards not only protect furniture, but they also make it hard for most babies to get a good biting angle. They also have the added benefit of protecting crawling babies as they start to explore the limits of their mobility. Of course, the house should be baby-proofed thoroughly, too.
Make sure the kid has a wide variety of teethers. A variety of shapes and textures is better – differently-shaped teethers let babies engage different parts of the jaw, and different textures are just more interesting. For safety, it’s a good idea to have nothing in the crib while the baby sleeps. Teethers or pacifiers that stay attached to the child should not be used when the child is left unattended. A tether can wind around their fingers, wrist, or neck, causing all sorts of dangerous situations. Parents can also massage their kid’s gums directly, with a finger or damp toothbrush.
One thing parents can’t do, though, is dissuade a baby from exploring with their mouths. They explore, they sense, they soothe, and they discover – and possibly strengthen their immune system unwittingly – with their mouth. It’s not just a comfort instinct for babies – it’s a trend that sticks with a lot of people well past infancy.
How to Stop a Kid From Chewing On the Crib
- Use oversized silicon guards. This doesn’t just protect the furniture; it’s difficult for babies to get their chompers around them.
- Give the kid something more appropriate to bite. Safe teethers (no small parts to come loose) in a variety of shapes and textures give the child a lot of options to explore and soothe.
- Massage their gums directly – this doesn’t just let a parent see which parts of their child’s jaw hurt. It helps soothe and relieve discomfort from teething.
