You wouldn’t have to experiment on children as such. You can follow children who were Brest fed and children who were bottle fed and compare the two.

It’s sort of a worrying study for me personally. Because bottle feeding only really works so well because you can microwave, both for cleaning and for heating, modern bottles so easily. If you have to go back to glass containers it’ll be a literal nightmare for most parents.

Not a parent, but curious: can’t you microwave glass booties ? I do microwave water in glass and don’t see problems. Is it the fragility of the glass ? In that case I guess any fabric protection can solve it ?

Not a parent, but guessing glass is bad because kids tend to throw things and glass is breakable.

I would use glass bottles to feed my kids, but I always held the bottle because the glass gets incredibly hot. I would wrap a towel around it to make it safe for me to hold.

By the time they could hold their own bottle we used plastic both for safe surface temperatures on the bottle and in case they threw it or dropped it as you mentioned.

The milk doesn't need to be that hot. Warm is fine, and if the bottle is that hot, I'd worry that the milk is too hot to drink.

I'm a parent and we are feeding our second child from glass bottles because of microwave+micro-plastic concerns. So far no bottle throwing, so we'll just see how far we get with these until the throwing starts. We'll probably also switch to glass food-containers for daycare once he starts going there.

They sell silicone bottle wraps that basically eliminate this concern.

So far, glass bottles have been fine for my kid.

I was guessing the commenter was referring to the expense of buying glass bottles, because they cost about double, and that "literal nightmare" was hyperbole.

What makes you think glass is safer in that regard?

See https://www.sciencedirect.com/science/article/pii/S277241662..., (Micro/nano glass pollution as an emerging pollutant in near future)

Now microplastics is all the rage so you see these studies, next you will see Micro-X whatever it is. The fact is that this is a headline grabbing study without any meaning and that did not show anything actually. They even say it in their study (but this does nto make headlines) that the study does not show at what concentration microplastics become a problem, just that at very unreasonably high concentrations they used it caoused cell death in petry cells. Almost Everything will cause cell damage at very high concentrations

So the dish washer is out? There is those sterilization things where you add a little water and put the bottles in steam for a few minutes. No idea what the risks there might be, but this is what my sister did, and I think it was plastic bottles at first, though she switched to glass with her second child because of micro plastic concerns etc.

If only there was some model, something like a human, preferably smaller, that maybe doesn't live quite as long. Perhaps it would be ideal if we could even hold it in our hands, and have a small space to contain many of these models.

Pfft who am I kidding, what an insane idea. People would just complain that the model has some unknowable flaw, and is therefore entirely useless.

Ok, it's too early in the morning. I can't figure out what you're alluding to.

Lab rats, I guess
