For bottle feed baby, what type of bottle do you prefer to use and why? (Glass or BPA plastic bottle)

Using Hegen bottles and I absolutely love them. - Easy to snap shut with one hand - Anti-colic air vent works wonder (really has less air bubbles), bubba burped less when I first made the switch - Twist-open (not one-handed operation), takes some getting used to, but it’s easy! - Square bottle means your bottle wouldn’t roll away when it topples Only started clouding a bit after 6mths+ of using, and the markings are scratching off :( but overall it’s a freaking awesome product!
