Most babies are picky. It is better to buy a few bottles and try them out to see what your tot likes, than to buy a ton of one brand. For those babies that are colicky we recommend Dr. Brown’s, but with these bottles comes extra time spent cleaning the many parts. If you are breastfeeding you will need the ones that go with whatever pump you have. Other brands we like are Avent and Born Free. Remember to register for a bottle drying rack, and maybe a brush to clean the bottles and nipples.
