I got these Tommee Tippee Natural Start bottles for my little one, and they were fantastic. The colorful design is super fun, and the natural latch feature really helped with the transition between breast and bottle. Convenient feature is that they are self sterilizing. Plus, the anti-colic valve was a game-changer for reducing air ingestion. They are like new, tried once. Found my baby liked a different brand. perfect for any newborn.
