Baby bottles?

Lily • 💕20 and pregnant with our first baby! I'm a bit of a princess at times💕
I'm buying some Dr Brown's glass bottles, then a load of his new plastic ones for traveling.
 
I also have Comotomo and a designer glass bottle as a gift, but can you recommend any other types or brands?
 
I think I have about 20 bottles, all different types, and want to get 10 more. How many bottles do I need? I have a mix of newborn and 3+ months.
