For those of you who are expecting a new bundle of joy and wondering which bottles are best for your baby, I highly recommend Dr. Brown's bottles. They are my absolute favorite.
Dr. Brown's bottles have a patented internal vent system that helps reduce bubbles. This helps reduce gas and colic. When you have a little one with gas pains or projectile vomit, you'll understand why these bottles are so important. I won't use any other bottle with my little girl.
Initially, I was breastfeeding my daughter but wasn't producing enough milk. Thankfully, I received some of the wide-neck bottles at my baby shower. The transition from breast to bottle was easier for the baby because the wide-neck nipples are made to be more like the breast. I wouldn't even use the skinnier Dr. Brown's bottles when we first started the transition to formula because it was easier on my daughter to use the shorter, chubbier bottles. :) I haven't been able to find more of the wide-neck bottles in any stores in our area, but I know you can order them on Amazon.
Example of the wide-neck bottles:
Dr. Brown's bottles do take a little longer to clean because of the extra pieces used to create the venting system, but a baby with less gas is well worth the effort. If you're planning to use formula or pump your own milk, I recommend putting these bottles on your registry.
