> Most human babies take 9-18 months to walk, and this is commonly attributed to the fact that human babies have immature brains that cannot mature due to birth canal constraints
I strongly doubt that human babies are physiologically capable of walking before 6-9 months regardless of their level of brain development. The entire baby is born many months "early" compared with other mammals due to the limitations of the human pelvis.
Hence me giving a range of 6-9 months. My niece was walking not long after 9 months, it's rare but not unheard of. A newborn baby simply wouldn't have the physical strength or rigidity, though.
Earliest I've seen was 9/10 months, that kid looked so strange to me, they could barely hold their head up as they tottered around like a drunk. I wonder if the parents promoted early walking?
People do that successfully, the problem is that if babies skip the crawling phase then it may cause learning disabilities among other things. Which is fascinating in the context of this conversation. The order in which things are learned can be very critical!
Yes, successful crawlers might walk later, kids that learn to bum-shuffle (propel forwards whilst sitting on their bottoms) might not crawl much.
Our eldest wasn't interested in crawling really and went almost straight to walking but not until about 14 months IIRC (it was > 10 years back).
We did baby sign (a sort of simplified BSL; would recommend) and some people suggested it would retard speech - same child modified a sign before 12 months and so could tell us he needed a poo/wee and we'd sit him on the potty to do it all before he was able to talk - saved me changing a lot of stinky nappies! Longitudinally, our kids used baby sign and did/are doing well at school and have all been ahead with language skills (but that's not accounting for confounding variables).
It's curious to see infant developmental stages becoming more and more to be compared to AI/robot development.
I think the problem is they lose a lot of weight early on (can roll over) and then begin to fatten up quickly. The calorie intake relative to body size is immense and for a few months a baby just doesn’t have the muscle strength to support its newfound fat composition (loss of ability to roll) in addition to their heads growing rapidly early on and not having the neck muscles developed yet.
Intel is an Old baby who walks with crutches. Intel delivered the 10nm Processor just 2 months back after a decade of failure. Their 7nm is still broken and so is there 5 and 3nm in research. And they hope to catch up to the competition by 2025 is a funny joke. Intel isnt a reliable delivery partner which is why Apple moved away to its own processors.
