Eli5: why do babies sit with perfect posture when they learn to sit, but the older you get, the worse it gets?

Babies sit straight up naturally. But the rest of us have to put effort in to having good posture, why?

Looks like I peaked at 6 months old, posture-wise. Time to give up and slouch into middle age.

Toddlers also lift with perfect technique. They get right up to their teddy bear, squat, hug the toy close to their chests with a straight back and use their legs to lift.

The explanation I’ve heard (although I don’t know if it’s true) is that they haven’t developed/strengthened their back muscles yet so they physically can’t lift with their back.

Because we as a species don’t emphasise the importance of posture. We emphasise chasing money, fame and sex which leads us to becoming miserable bent over hunchbacks.

I mean- they don’t all have good posture. I work with infants and toddlers and some of them are a little wonky out of the gate. 😂

But if I had to guess the answer I’d say it’s bc it requires so much more of their energy and effort to stay upright, so they are engaging their muscles more deliberately. As they get older and sturdier they don’t need to do that as much.

Yet some “fitness professionals” use babies as example and emphasize on the fact we should squat and sit like them while completely ignoring the variables of muscle tone ,body proportions and weight, bone origins and insertions, center of gravity, genetics, etc.
