Why Do Babies Put Their Hands In Their Mouth? Dealing With Your Baby’s Obsession With Hand Sucking & Chewing

I was aware of a baby’s obsession with thumb sucking but never with hand chewing, which added to my concern.  My little one’s obsession with his hands started at the age of 3 months. At first, I ignored it, but it grew into an addiction, as every time I tried getting his hand out of his mouth he would start crying non-stop. This had me worried sick. Is he hungry? Is he hurting somewhere? Is he teething? A lot of questions started popping up in my mind, which I had no answer to. So, I decided to find a logical explanation for this behavior and tips on dealing with this obsession of my son, and here’s what I found.

According to the experts, babies start chewing on their hands because it’s their first discovery about themselves. Babies are neither aware of their body parts, nor do they know how to control them. So, after a few months, they start discovering their bodies with their hands. According to Sahira Long, the Medical Director of Children’s Health Center Anacostia in Washington, D.C, Babies start their expedition of discovery by exploring mouths, and hands act as the best tool available to do so. Another, a lot more logical explanation for this obsession, is that your baby must have started teething. The reason why your baby could be chewing on hands, is that hands are very helpful for the teething process, and it’s the only available tool for them at that point which is with them 24/7. The whole process of putting their hands inside the mouth is a mere effort of discovering and controlling their body parts. Pediatricians advise parents to not get concerned about the little unconventional things that their babies do because they are part of their growth. To get accustomed to the new world babies need to discover as much as possible, with bodies being the first step in that direction. Pediatricians like to call this, a first milestone for the baby as he learns hand-to-mouth connection, through sucking or chewing on hands.

Why do babies suck or chew on their hands?

To understand the reason why your baby is obsessed with chewing or sucking on his hands, you’ll need to do a little bit of research on your part. Sometimes these reasons will depend more on the age or the developmental phase your little one is going through. Here are the best logical explanations as to why babies suck or chew on their hands.

Self-relieving

We know that babies tend to suck their thumbs and, in this case, their hands, to soothe themselves. Babies tend to fall asleep during breastfeeding or feeding through a bottle, which is why they associate this sucking sensation with relaxation or time to sleep. This is why you’ll find your little one sucking on hands during sleep.

This new world with new people and noise can get overwhelming for your baby, and sucking on their hand helps them handle these simulations. Sucking also makes your baby feel safe, which is why they love to suck round the clock.

Some older babies, infants around 8-9 months, can also be found sucking on their hands because it helps them relax and sleep peacefully at night. You will also notice your baby sucking on his hands when he is a little agitated or feeling under the weather. In the end, you can know that this is one of your baby’s relaxation technique, and just let them be!

Hungry

If your newborn baby is sucking on his hands, then this could also mean that he is hungry. Your baby is doing this because of the familiar sensation of sucking that he gets through breastfeeding. As he cannot tell you in words, he starts to suck on fingers to satisfy his hunger, thinking that sucking on fingers will give him milk as well. You can take this cue as the time for another feeding.

Newborn babies tend to give their hunger cues through their mouths. They might open and close their mouth or smack their lips to give you a sign that they are hungry. By feeding them right after, you can also verify if they were giving you a cue for another feeding or not.

Some babies that are going through the developmental phase tend to chew or suck on their hands, even after feeding.

Teething

Teething is the most common reason among babies for chewing on hands and most babies start teething between 4-7 months. If your baby is drooling quite a bit, being cranky, and is waking up in the middle of the night, then he’s probably going through a teething phase. Know that it’s a tough time for them and let them chew on their hands to alleviate their pain.

Teething can be a painful process followed by irritation in gums and a lot of drooling. Thus, chewing on hands or fingers against those sore spots relieves the pain.

Exploration

I understand that adults don’t find hand sucking entertaining but for our little angels, this is the most fascinating and playful act. The newly found freedom of being able to control their hands makes our babies obsessed with them for some reason.

The only exploration that our babies can undergo at this stage is through their hands, as their sense of hearing and vision is not fully developed yet. He depends on the sensation of taste to understand the world around him.

Also, your baby has just started figuring out how amazing and multitasking their hands can be. They cannot only touch things but can pick them up and put them in their mouths as well. The ability to sense temperatures and tasting new things is how their journey to exploring a new world begins, this makes it kind of normal to get this obsessed with their hands.

Boredom

Newborns have quite a busier routine than we can imagine, involving feeding, pooping, crying, and sleeping, so they do not get bored at all. But as soon as they start staying up for longer periods, boredom starts hitting them.

This boredom can also trigger sucking or chewing on hands, as it keeps them busy and occupied. A tip here is to try changing up your baby’s scenery when you feel that he is chewing on his hands out of boredom.
