Tommee Tippee Natural Start vs. Lansinoh Anti-Colic Bottles

Tommee Tippee Natural Start Anti-Colic and Lansinoh Anti-Colic are two of the most commonly recommended bottles for gassy, fussy babies. Both claim to reduce air intake during feeds. Both feature breast-like nipples designed to ease the transition from nursing.

The honest truth: both are good bottles. Most babies will accept either one. But the differences in nipple flexibility, venting design, and ease of cleaning matter more than marketing suggests — especially if you're switching a breastfed baby to a bottle or dealing with a baby who struggles with gas.

We compared the nipple design, anti-colic mechanisms, assembly, cleaning, and price so you can pick the right bottle without buying six different brands first.

For guidance on how much to put in the bottle, see our baby feeding chart.

The nipple is the single most important part of any baby bottle. It determines whether your baby accepts the bottle, how much air they swallow, and whether breastfed babies develop a preference that makes nursing harder.

Tommee Tippee Natural Start uses a wide, dome-shaped silicone nipple. It's breast-like in appearance and feel, with a firm but flexible texture. The shape is symmetrical — baby can latch from any angle. It works well, but the nipple is firmer than a real breast and doesn't stretch as dynamically.

Lansinoh NaturalWave nipples were designed with input from lactation consultants. The nipple is wider, flatter, and significantly more flexible. It stretches and compresses in the baby's mouth much like breast tissue does, encouraging the same wave-like tongue motion babies use during nursing. Clinical testing has shown it helps maintain breastfeeding patterns.

If your baby is exclusively bottle-fed, either nipple will work fine. If you're combo-feeding or introducing a bottle to a breastfed baby, Lansinoh's NaturalWave nipple is the stronger choice for reducing nipple confusion.

Both bottles are designed to separate air from milk so your baby swallows less gas. They do it differently.

Tommee Tippee uses a venting tube — a thin straw-like piece that sits inside the bottle. As baby drinks, air travels up through the tube instead of mixing with the milk. It works well, but the tube is narrow and requires a small brush (included) to clean properly. Some parents find it fiddly.

Lansinoh uses an Air Ventilation System (AVS) — a vented insert that sits at the bottom of the bottle. Air enters through the base and stays separated from the milk above. There's no tube to scrub, but the AVS piece itself needs to be cleaned separately after each use.

Both systems reduce air intake effectively. The practical difference is in cleaning: Tommee Tippee's tube is harder to scrub but easy to assemble. Lansinoh's AVS is easier to clean but adds a bottom piece you need to seat properly to avoid leaks.

Neither system eliminates gas entirely. If your baby is still gassy after switching bottles, talk to your pediatrician — the issue may be feeding technique, flow rate, or something unrelated to the bottle.

You will wash baby bottles multiple times a day, every day, for months. Ease of cleaning matters more than any spec sheet.

Tommee Tippee Natural Start has four parts: bottle, nipple, collar, and venting tube. The bottle itself is easy to wash — the wide neck lets you get a brush inside without trouble. The venting tube is the weak spot. It's narrow, and milk residue can build up inside if you don't use the included tube brush. Some parents skip the tube entirely after the colic stage passes.

Lansinoh Anti-Colic also has four parts: bottle, nipple, collar, and the AVS base insert. The straight-walled bottle is simple to clean. The AVS piece is flat and easy to rinse — no tube brush needed. The trade-off is that you must seat the AVS piece correctly when reassembling, or the bottle may leak from the bottom.

Both are top-rack dishwasher safe. For sterilizing, both work with standard microwave steam sterilizer bags or electric sterilizers.

Lansinoh bottles run about $1–$2 less per bottle than Tommee Tippee across all sizes. Over a set of six to eight bottles — which is what most parents end up needing — that's a $6–$16 difference. Meaningful but not dramatic.

Where cost really adds up is in replacement nipples. As your baby grows, you'll need to move up in flow rate. Both brands charge $5–$8 for a two-pack of nipples. Since you can't swap between brands, you're locked into one nipple ecosystem once you pick a bottle.

Tips to save:

• Buy starter sets when available — both brands offer bundle packs with multiple sizes and flow rates.
• Watch for registry completion discounts at Target, Amazon, and Buy Buy Baby.
• Don't overbuy upfront. Start with two or three bottles to make sure your baby accepts them before stocking up.

If you want a well-rounded anti-colic bottle with wide retail availability, the Tommee Tippee Natural Start Anti-Colic (~$7/bottle in a 3-pack) is a strong pick — compact shape, reliable venting tube, and easy to find at nearly any store. The variable-flow nipple option is a nice bonus as your baby grows.

If you're prioritizing a smooth breast-to-bottle transition, the Lansinoh Anti-Colic Bottles (~$6/bottle in a 3-pack) are hard to beat — the NaturalWave nipple is one of the most breast-like on the market, and the bottom-vented AVS system means no tube to scrub. Slightly cheaper, too.

Our honest advice: if your baby is exclusively breastfed and you're introducing a bottle, start with Lansinoh. If your baby is formula-fed or you want the widest availability, Tommee Tippee is a safe bet. Either way, buy a small pack first.

Both the Tommee Tippee Natural Start Anti-Colic and Lansinoh Anti-Colic are well-designed bottles that do what they promise — reduce air intake and offer a breast-like feeding experience.

Lansinoh Anti-Colic edges out for breastfed babies transitioning to a bottle, nipple flexibility, ease of cleaning (no tube), and price.

Tommee Tippee Natural Start edges out for retail availability, bottle grip and shape, variable-flow nipple option, and aesthetic design.

For most families, the deciding factor is nipple acceptance. Babies are particular, and the "best" bottle is whichever one your baby will actually drink from without a fight. Start small, test both if needed, and don't feel locked in.
