Bad posture can lead to back pain. Why is a curved back bad posture when we spend the first months of our lives with a that posture?

In utero you do not have to fight the force of gravity through standing up. Your bones are not fully calcified and are more supple to help w the birthing process, etc.

Something like this, if not exact, I see in weight lifting circles is the notion that one should squat like a toddler. I have a teo year old and she does have a pretty natural and impressive squat form. The issue is, her femur/hip to leg ratio is cartoonish compared to an adult humans. We should not squat like they do bc of our different body structure. Adult squatting mechanics are different. The same is true w the spine; a developing baby is supported on all sides by a fluid filled womb and has no need to have a straight spine like a child/adult does.
