Best bottle for breastfed baby/pumped milk?

Visceral Mercenary • May you find your worth in the waking world.

Which bottles worked for you? I could not get either of my kids to take pumped milk from a bottle. I'm due with number 3 in July and I have plenty of time to buy different types of bottles here and there. Which ones worked best for you? Especially if you have a picky baby that it took several bottles to find the right one.
