We love our Cherubbaby glass bottles. They are light to hold but tough to break, we have been using the same bottles for more than a year. It is easy to warm formula or solid foods in the glass bottle than any plastic bottle with a electric milk warmer. The wide neck design just make them easy to be clean. The protection sleeve is not only practical and looks good in bright colour but also helps the little hands to grab easily. The best thing is I know my baby is safe to use the bottles without any nasty plastic components that may leak into his drink or food.
