I know it's certainly possible to make glass baby bottles.

It's a minor point but bottles that provide any insulating value are sort of worrying to use as the risk of giving a baby a hot drink increases and glass baby bottles are sometimes thick glass. It turns out that getting up for the 9th time, totally exhausted, makes reliably noticing anything hard. Disclaimer: I have only used one glass baby bottle ever

If your child is tolerant, just don't heat the bottle. After trying various warming schemes with screaming twins waiting for food, we just began giving them their food right from the fridge and they didn't complain. Haven't warmed a bottle since.*

* for various reasons we fed with formula only and premeasure formula and water before bed for quick mixing in the middle of the night.

We gave our kid formula with room temperature water for the entire duration of him being on formula. We never heated it ever, and he was fine with it.

With my first two children, they took it at room temperature. Third was born in the winter and tap water was considerably colder and he wouldn't take it.

I would heat an exact amount of water for a specific time in the microwave to get a specific temperature. I started reducing the time in the microwave by one second a day and he never noticed.

This was exactly the solution we got to. The do-gooders were incensed at the system. Not having to heat it up or fart about at night (once the child is trained) is excellent. And as a bonus, our tap water is very clean, so sterilized bottle and tap water for formula. Refrigerated is even better, well done! Question. Twins, have you ever slept?

How much would you kill for a barista style formula dispenser? :-) First world problem, I know, but I always imagined, 'click-click' and getting exactly the right amount. New fridges have water dispensers where you can set the ounces on the door, and they dispense exactly that amount. I wonder if they can set the temperature precisely too? I guess just another way our kids will not face the same set of challenges. (Not necessarily 'have it better' just applying their energy differently with a whole different set of expectations to go along with it)

Nestle has already done it: http://www.theguardian.com/lifeandstyle/2011/may/26/nestle-l...

Why do you heat drinks for the baby? I never understood why. It's the same nutritional value, and it becomes really messy when you're outdoors if they expect it.

Allow a drop to fall on the bottom of your wrist, that'll tell you quite quickly.

We have about 10 Life Factory bottles on rotation for twins. They have silicone sleeves, and have only had one break over the course of a year (it fell from a small distance without a cap and hit the exposed top and shattered; others have fallen without incident).

Glass or ya know, glass...
