Why Do Babies Learn to Crawl Before They Walk?

Fabian van den Berg:

Babies walk or dance before they crawl actually, well sort of, you’ll see.

Babies are amazing little creatures. They are very different from adults and should be treated as such. They aren’t born as blank slates, though; a lot of things are innate, and a lot of things are learned. And boy can they learn—not just by watching others do things, but also by experimenting. There’s a reason why early developmental psychologists called them "little scientists." They will form strategies on their own, test them out, and choose the best one.

We’ll focus on walking for now.

Newborns come fully equipped with a stepping reflex. If you happen to have a newborn at your disposal you can try it out (but support the head). By dragging them a bit over a surface, the feeling of their feet/soles touching will initiate a stepping reflex, it looks like they’re walking. (Don’t let go though, they are definitely not ready to stand on their own yet and will fall down.)

The reflex tends to be present for the first two months, sometimes returning right before they start to walk. It’s thought that the reflex helps to train the muscles and motor nerves. The reason why it disappears is thought to be because the legs become too heavy, the muscles grow faster than their strength. Basically, they become too chubby and the reflex doesn’t work anymore.

In a way, they are born with the ability to walk or dance (it differs a bit from baby to baby), but then lose it again because they grow so fast.

There are a lot more interesting and fun baby reflexes, like swimming and grasping, but that’s for another answer.

That brings us to toddlers and locomotion: Many parents will attest they looked forward to their baby being able to move on their own, and as soon as they did they missed the times the little bugger would stay put.

Infants can be very motivated, which is where the little scientist pops up. Having toys or anything interesting looking sitting around is very tempting. Kids love touching things, they explore, and they really want to go there… But how…

Should they wait for the big person to either bring them there or bring the shiny to them? No, of course not. They can move now—so off they go!

They will experiment and explore a lot of different ways of getting around. A very popular one is scooting. They are laying there (they’re good at that), but they want to be elsewhere. Almost all children will solve this conundrum by pulling or pushing themselves using their hands [and] scooting or shuffling across the floor. A popular and funny variation is scooting on their bums. If they can sit, they’ll prefer to sit and just use their arms and legs to push themselves around.

It’s not uncommon for children to be in this stage until they learn how to walk. It really is a matter of what works best for them.

Crawling is merely a more advanced version of scooting. Their legs become stronger and they are able to control them better. They will happen upon crawling by trial and error, and find that it can bring them from Point A to Point B faster than scooting.

The logic is simple to follow: I want to go over there, crawling works best, so crawling it is.

Strategy use is very common in children, you see it in many aspects. They will try out new things, compare it to old things, and decide on whatever works best. In the case of crawling it’s mostly about speed. But as I said before, not all kids crawl. For some scooting works best, and they’ll use it until they learn how to walk.

It’s also not strange to see them use different strategies, sometimes crawling, sometimes scooting. Usually this occurs when they are learning and experimenting with new strategies.

Children don’t need examples to learn, they are very capable on their own. They will try and discover things like the small scientists they are.

Crawling is one of those things. They don’t need to see it, they discover it, realize it works better than what they had before, and start using it more and more until something better (like walking) comes along.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

Why Are Common Graves Called Potter’s Fields?

For centuries, regions around the world have maintained common graves called potter’s fields, where they bury unidentified victims and impoverished citizens who couldn’t afford their own cemetery plots. The term potter’s field has been around for just as long.

The earliest known reference to a potter’s field is from the Gospel of Matthew, which historians believe was written sometime during the 1st century. In it, a remorseful Judas gives the 30 silver coins he was paid for betraying Jesus back to the high priests, who use it to purchase a “potter’s field” where they can bury foreigners. It’s been speculated that the priests chose land from a potter either because it had already been stripped of clay and couldn’t be used for farming, or because its existing holes and ditches made it a particularly good place for graves. But Matthew doesn’t go into detail, and as the Grammarphobia Blog points out, there’s no evidence to prove that the original potter’s field was ever actually used for its clay resources—it could’ve just been a parcel of land owned by a potter.

Whatever the case, the term eventually caught on as English-language versions of the Bible made their way across the globe. In 1382, John Wycliffe translated it from Latin to Middle English, using the phrase “a feeld of a potter,” and William Tyndale’s 1526 Greek-to-English translation of the passage featured “a potters felde,” which was altered slightly to “potters field” in King James’s 1611 edition.

Around the same time, a new definition of potter was gaining popularity that had nothing to do with pottery—in the 16th century, people began using the word as a synonym for tramp or vagrant. According to the Oxford English Dictionary, it was first written in a 1525 Robin Hood tale, and William Wordsworth mentioned it in his 1798 poem “The Female Vagrant.” It’s likely that this sense of the word helped reinforce the idea that a potter’s field was intended for the graves of the unknown.

It’s also definitely not the only phrase we’ve borrowed from the Bible. From at your wit’s end to a fly in the ointment, here are 18 everyday expressions with holy origins.
