Good baby bottles should be easy to clean and sterilize. Maintaining cleanliness is crucial for your little one's health. Additionally, it should have a sturdy and leak-proof design, which will help prevent any mishaps during feeding time. A comfortable grip is also important - after all, your hands may be holding that bottle for quite some time! Finally, look for a bottle with a nipple that mimics breastfeeding as closely as possible; this will help your baby transition from breast to bottle.
