Philips Avent Natural Response vs Dr. Brown’s: which baby bottle is right for your baby?

By / 3 November 2026

Researched, not hands-on tested. Specs checked on Philips’ US website (October 31, 2026) and Dr. Brown’s US website (November 1, 2026), with key specs re-checked on both sites on November 2, 2026. How we research products.

You have narrowed it down to the two bottles everyone names, and the reviews only make it harder: one camp says Dr. Brown’s is the only thing that helped with gas, the other says Avent is so much easier to wash. This Avent Natural Response vs Dr. Brown’s comparison puts the official specs side by side, explains the one real design difference (where the vent sits), and helps you pick based on your baby and your routine, not on marketing.

More on feeding: our baby feeding guides.

Quick answer: which is better, Dr. Brown’s or Avent?

  • Neither is proven better. The NHS says there is no evidence that one type of teat or bottle is better than any other, and the AAP says trial and error tends to work best.
  • Pick the Philips Avent Natural Response if you want fewer parts, a valve in the nipple and flows chosen by your baby’s drinking pace.
  • Pick Dr. Brown’s Options+ if you want an internal vent system and more nipple levels, and you are fine washing two extra vent pieces.
  • Buy one or two bottles first and see how your baby drinks before buying a full set.

The real difference: where the air goes

Both bottles try to stop a vacuum building up as your baby drinks. Philips puts a valve in the nipple, so the bottle has four simple parts. Dr. Brown’s routes air through a tube inside the bottle, which adds two pieces and asks you to hold the bottle at about 45 degrees, fill only to the line and not shake formula with the vent in. If those steps are skipped, Dr. Brown’s own FAQ says the bottle can leak.

Flow is the other big choice. Philips labels its nipples by pace, so you watch your baby and move up or down a number. Dr. Brown’s has more small steps at the start, including Preemie and Newborn levels. For a breastfed baby, a slow flow and paced feeding matter more than the brand; see our guide to bottles for breastfed babies.

Pick the Philips Avent Natural Response if…

  • you want the fewest parts to wash and assemble at 3 a.m.;
  • you already pump with a Philips Avent pump, since Philips says its parts mix and match;
  • your baby pauses a lot during feeds and you like a nipple Philips says releases milk only when your baby sucks;
  • you want an 11 oz size later on.

Pick Dr. Brown’s Options+ if…

  • you want an internal vent you can remove later as feeding develops;
  • you want Preemie or Newborn nipple levels below Level 1;
  • you want a choice of narrow or wide-neck bottles;
  • you do not mind the extra vent pieces and the small cleaning brush.

If gas or colic is the reason you are comparing

Vented bottles are one of several things the AAP mentions for a gassy baby, along with burping and feeding position. No bottle cures colic. Before buying a full set, read what anti-colic bottles can and can’t do.

For soothing steps beyond the bottle, see our baby colic guide.

Safety notes for both bottles

  • Recall check (November 2, 2026): the CPSC recall database lists no recall of Philips Avent or Dr. Brown’s bottles or nipples. The brand recalls it does list are other products: Philips Avent Digital Video Baby Monitors (2023, burn hazard), Dr. Brown’s Natural Bottle & Dish Soap (2017) and Dr. Brown’s Lovey pacifier and teether holders (2018, choking hazard).
  • Never prop a bottle or leave your baby alone with it, and do not put your baby to bed with a bottle (CDC).
  • Use only the maker’s own nipples on each bottle; both manuals say other nipples may not fit or may leak.
  • Never warm milk in a microwave; it can create hot spots (CDC and Dr. Brown’s manual).
  • Clean bottles after every feeding. The CDC advises sanitizing at least daily if your baby is under 2 months, was born early or has a weakened immune system.
  • Glass bottles can break; inspect them before each use.

When to talk to your doctor

  • Your baby cries for hours most days, or the crying sounds different from usual.
  • Your baby often coughs, chokes or gags during bottle feeds, or vomits forcefully.
  • You see fewer wet diapers than usual or are worried your baby is not drinking enough.
  • Call 911 if your baby has trouble breathing or turns blue.

Frequently asked questions

Is Dr. Brown’s better than Avent?

Not in any way that has been proven. The NHS says there is no evidence that one type of bottle or teat is better than another. Dr. Brown’s has an internal vent and more nipple levels; the Avent Natural Response has fewer parts and a valve in the nipple. The best bottle is the one your baby drinks from calmly.

Is Dr. Brown’s or Avent better for colic?

Dr. Brown’s says its vent system is clinically proven to reduce colic, and Philips says its valve keeps air away from the tummy. Both are manufacturer claims. The AAP lists vented bottles as one option for gas and says trial and error tends to work best; no bottle cures colic.

Can you use Avent nipples on Dr. Brown’s bottles?

No. The Dr. Brown’s instructions say to use only Dr. Brown’s nipples, because other brands may leak or flow too fast or too slow, and the Philips manual says its bottle parts are compatible only with Philips Avent Natural nipples.
