# Protecting a Glass Baby Bottle From Breaking

How can a glass baby bottle be protected from breaking?

Lifefactory 4oz Glass Baby Bottle: The silicone sleeve protects the bottle from breaking when dropped; one parent reportedly dropped it on concrete with no chip\. For freezing, store upright, do not fill to the top, and leave at least 2oz/58 ml of open space from the neck to allow for expansion and prevent glass breaking\. Lifefactory 9oz Glass Baby Bottle: Feedback was mixed: users liked the glass construction, silicone sleeve and perceived quality, but the narrow opening was a major drawback\. The borosilicate baby bottle can transition from the freezer to boiling water\. Dr\. Brown's Anti\-Colic Options\+ Narrow Glass Baby Bottle: The glass bottles are heat and thermal shock\-resistant and can withstand hot and cold temperatures and gradual temperature changes\.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from\. A dash means no checked fact fills that cell\.

Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
