Don’t fall for the marketing on baby bottles I know it’s tempting when you see words like “breast-like” or bottles shaped like a b**b, but appearance is not function. Many of the bottles designed to look like a breast actually function the least like one once they’re in your baby’s mouth. At the breast, babies take a wide mouthful of tissue, create a seal, and use a coordinated wave of the tongue and jaw (not just their lips) to move milk with both suction and compression 
When a bottle ni**le is short, narrow, or has that abrupt “shoulder” shape, babies often can’t get a deep latch. They default to a shallow, straw-like suck on just the ni**le. And yes, they can still get milk that way, but it’s not optimal. That pattern shifts the workload to the lips and cheeks instead of the tongue and jaw, which can show up as lip blisters, dimpling cheeks, more air intake, and less efficient feeds over time 
Even more importantly, those repetitive movement patterns shapes baby’s oral development and jaw growth long term
Here’s the part that gets missed in marketing: a baby being able to “latch” doesn’t mean it’s a functional latch. A shallow latch is still a latch, but it’s not doing your baby (or your breastfeeding relationship) any favors. Bottles that allow milk to flow with mostly compression can actually teach a chomping pattern instead of the more coordinated suck babies use at the breast. That’s where we start to see challenges going back and forth between breast and bottle
What we’re really looking for is function over marketing. A ni**le with a gradual, tapered shape is better, like the Pigeon, Lansinoh, Gulicola, and Evenflo Balance to name a few
