Dr. Brown's Options+ 対 Natural Flow:赤ちゃんに最適な哺乳瓶システムはどちら?

Choosing the right baby bottle can feel overwhelming, especially when you're faced with two popular systems from the same trusted brand. Dr. Brown's offers both the Options+ and Natural Flow lines, each designed to reduce colic and gas while supporting healthy feeding. But what sets them apart, and which one will work best for your little one?
In this detailed comparison, we'll break down the key features, venting technologies, cleaning routines, and age recommendations for Dr. Brown's Options+ and Natural Flow bottles. By the end, you'll have a clear understanding of which system aligns with your baby's needs and your parenting lifestyle.
Understanding the Venting Technology: Options+ vs. Natural Flow
Both Dr. Brown's Options+ and Natural Flow bottles use a patented internal vent system to reduce air ingestion, which is a primary cause of colic, gas, and spit-up. The Natural Flow system features a fully integrated vent tube and straw that creates a vacuum-free feeding experience, mimicking the natural flow of breastfeeding. This design helps maintain the nutritional integrity of breast milk by minimizing air exposure.
The Options+ system takes this a step further by offering a two-in-one design. You can use it with the vent tube and straw for maximum colic relief, or remove the internal components to convert it into a standard bottle for older babies who no longer need the extra venting. This flexibility makes Options+ a versatile choice for parents who want one bottle system that adapts as their baby grows.
- Natural Flow: Integrated vent tube and straw for consistent anti-colic performance from day one.
- Options+: Two-in-one design — use with vent for newborns or without for older babies transitioning to standard bottles.
Cleaning and Maintenance: Which Bottle Is Easier to Keep Clean?
One of the most common concerns among parents is the number of parts involved in anti-colic bottles. The Natural Flow system includes a vent insert, a straw, and a nipple, which means three separate pieces to wash and sterilize. While effective, this can be time-consuming, especially during late-night feedings.
The Options+ system offers a slight advantage here because of its convertible design. When used without the vent tube, it becomes a simple two-piece bottle (nipple and bottle), making it much quicker to clean. For parents who prefer to use the vent system, the Options+ parts are also dishwasher safe, and you can use the Dr. Brown's Options+ Dishwasher Basket for Narrow Baby Bottle Parts to keep everything organized and secure during the cleaning cycle. This basket holds nipples, vents, and straws in place, preventing them from falling through the dishwasher rack.
- Natural Flow: 3 parts per bottle (nipple, vent insert, straw) — thorough but more pieces to wash.
- Options+: 2 or 3 parts depending on configuration — vent system can be removed for simpler cleaning.
- Tip: Use a dedicated dishwasher basket to keep small parts from getting lost or damaged.
Feeding Stages: When to Use Each System
The Natural Flow system is an excellent choice for newborns and young infants who are exclusively bottle-fed or combination-fed. Its consistent venting helps reduce colic symptoms from the very first feeding. Many parents find that their babies take to the Natural Flow nipple shape easily, as it closely resembles the breast's natural feel and flow.
The Options+ system shines during the transition period. Around 4 to 6 months, many babies begin to outgrow the need for intensive venting, and the ability to remove the vent tube makes the bottle lighter and simpler. For older babies who are learning to self-feed, the Options+ bottles can be paired with sippy spouts or soft spouts. For example, the Dr. Brown's Milestones Narrow Sippy Spout Bottle with Silicone Handles, 8 oz/250 mL is a natural next step after using Options+ bottles, offering a spill-proof transition to independent drinking while still using the same bottle body.
- Natural Flow: Best for newborns and young infants (0–6 months) who need consistent anti-colic support.
- Options+: Ideal for babies 4 months and older who are transitioning to self-feeding or standard bottles.
- Milestones line: Compatible with Options+ bottles for a seamless transition to sippy cups.
Nipple Flow Levels and Compatibility
Both systems use Dr. Brown's signature silicone nipples, which are available in multiple flow levels (Preemie, Level 1, Level 2, Level 3, and Y-cut for thicker liquids). The nipples are interchangeable between the Options+ and Natural Flow bottles, so you can mix and match as needed. This is especially helpful if you already own a set of one system and want to try the other without buying all new nipples.
For newborns, the Level T (transitional) nipple is often recommended. Dr. Brown's Natural Flow Narrow Baby Bottle Silicone Nipple, Level T, 6-Pack provides a slow, gentle flow that mimics breastfeeding and reduces the risk of overfeeding. As your baby grows, you can step up to higher flow levels to match their increasing feeding speed and appetite.
- Nipples are cross-compatible between Options+ and Natural Flow bottles.
- Level T (transitional) is ideal for newborns; Level 1 for 0–3 months; Level 2 for 3–6 months; Level 3 for 6+ months.
Specialty Feeding and Travel Considerations
For parents of premature babies or infants with feeding difficulties, Dr. Brown's offers the Specialty Feeding System, which includes a specially designed nipple and bottle to support slower, more controlled feeding. This system works with both Options+ and Natural Flow bottles, giving you flexibility based on your baby's specific needs.
When traveling, the Options+ system's ability to remove the vent tube makes it more compact and easier to pack. You can also use the Dr. Brown's Microwave Sterilizer Bag for quick sterilization on the go — it holds up to four bottles and their parts, and works in any standard microwave in just 90 seconds. This is a game-changer for busy parents who are constantly on the move.
- Specialty Feeding System: Designed for premature babies or those with feeding challenges.
- Travel tip: Use a microwave sterilizer bag for quick, portable sanitization of bottle parts.
Ultimately, both Dr. Brown's Options+ and Natural Flow systems are excellent choices for reducing colic and supporting healthy feeding. If you're looking for a bottle that grows with your baby and offers cleaning flexibility, the Options+ is a smart investment. If you prefer a dedicated anti-colic system with consistent performance from day one, the Natural Flow is a reliable classic. Whichever you choose, your baby will benefit from the thoughtful design that has made Dr. Brown's a trusted name in infant feeding.
