Choosing a baby bottle for a newborn can feel overwhelming. There are endless promises—anti‑colic, breast‑like nipple, BPA‑free, easy to clean—but not every product lives up to the marketing.

In this review, I take a close look at the Thyseed PPSU Natural Anti‑colic Baby Bottle and evaluate it against key criteria parents actually care about: safety, design, feeding experience, cleaning, value for money, and long‑term use.

Quick Overview

• Product: Thyseed – PPSU Natural Anti‑colic Baby Bottle
• Age range: From 0+ months (newborn-friendly)
• Available sizes: 160 ml and 240 ml
• Material: BPA‑free PPSU (BASF Ultrason®)
• Positioning: Anti‑colic, breastfeeding‑friendly bottle for newborns and young infants

1. Who Is the Thyseed PPSU Anti‑colic Bottle For?

Thyseed Baby Bottle positions this bottle specifically for newborns and young babies who:

• Struggle with gas, colic, or spit‑up
• Are breastfed and bottle‑fed (mixed feeding) and need a gentle transition between breast and bottle
• Need a bottle that supports a natural latch and controlled milk flow

With a 160 ml size aimed at 0+ months and a larger 240 ml size for older babies, the range is clearly designed to grow with your baby’s feeding volume.

2. Materials & Safety: What Is This Bottle Made Of?

When it comes to newborn products, material safety is non‑negotiable. Here the Thyseed bottle scores strongly.

2.1 PPSU Bottle Body

The bottle body is made from BASF’s high‑performance thermoplastic Ultrason® (PPSU). PPSU is widely used in premium baby bottles because it is:

• BPA‑free and BPS‑free
• Highly heat‑resistant (suitable for boiling, steam, and many sterilization methods)
• Durable and impact‑resistant, less likely to crack compared to regular plastic
• More stable under repeated sterilization than standard PP

For parents who prefer the practicality of plastic but want something safer and more robust than conventional materials, PPSU is one of the best options currently available.

2.2 Silicone Nipple

The nipple is made from soft, flexible silicone with a wide, textured base. While the product listing doesn’t go into extreme technical detail, it is clearly positioned as:

• Breast‑like in shape and feel
• Designed to support a natural latch for newborns
• In line with current safety expectations, the nipple is BPA‑free and free from common harmful additives.

Verdict on Safety: From a materials perspective, Thyseed checks the right boxes: premium PPSU, BPA/BPS‑free, and suitable for the high‑heat cleaning routines many parents rely on.

3. Design & Feeding Experience

A safe bottle is essential, but design details determine whether babies actually accept it and whether it really helps with colic.

3.1 Anti‑Colic Base Vent

One of the standout features of this bottle is its built-in anti‑colic vent in the base.

• The integrated base venting system helps minimize air intake during feeding
• Less swallowed air can support a more settled tummy and reduce fussiness, gas, and spit‑up
• Unlike some bottles that rely entirely on nipple vents or complex inner tubes, Thyseed uses a base vent system while keeping the overall number of parts low.

In practice, a well‑designed base vent allows air to enter the bottle from the bottom, preventing vacuum formation and reducing the amount of air that ends up in the baby’s stomach. This design concept is similar to other well‑known anti‑colic brands, which is a positive sign.

3.2 Breastfeeding‑Friendly Nipple

Thyseed clearly markets this as “Breastfeeding Friendly”, and the nipple is felt as soft and flexible silicone with a wide, textured base to help newborns latch naturally. It is intended to ease the transition between breast and bottle.

This is particularly important for:

• Babies who are primarily breastfed but occasionally take a bottle
• Parents who worry about nipple confusion or poor latch with traditional bottle nipples

3.3 Responsive, Choke‑Resistant Milk Flow

Another interesting claim is “Responsive Milk Flow”. Milk flows only when the newborn actively sucks, supporting a natural drinking rhythm and helping prevent overwhelming flow.

The bottle is described as “choke proof”, indicating a focus on flow control. For newborns, a slow, controlled flow is crucial to avoid coughing, gagging, and overfeeding.

3.4 Multiple Nipple Flow Levels

Thyseed offers 4 nipple flow levels, tailored to different stages, starting from a slow newborn flow and moving to faster flows as the baby grows. This allows parents to keep using the same bottle body while simply upgrading the nipples.

4. Ease of Cleaning & Everyday Maintenance

Many anti‑colic bottles earn complaints for being difficult to clean due to complicated vent systems. Thyseed tries to address that.

4.1 Only Four Main Parts

A key phrase in the product description is: “Only 4 parts – easy to clean and reassemble.”

This suggests that despite having a base vent, the overall structure is kept deliberately simple. Fewer parts generally mean less time scrubbing, fewer places for milk to get trapped, and lower risk of incorrect reassembly.

4.2 Fully Disassemblable

Because the bottle breaks down into only a small number of parts (Body, Nipple, Collar, Base vent), you can fully disassemble it for thorough cleaning. Being able to reach every surface is important to prevent milk residue buildup, odors, and bacterial growth.

4.3 Compatible with Common Cleaning Methods

Care instructions specify that the bottle is safe in microwaves, boiling water, dishwashers, and sterilizers (including steam systems). Combined with a wide neck design, this makes the Thyseed bottle very convenient for daily use.

Verdict on Cleaning: Compared to many anti‑colic bottles with complex internal valves or tubes, Thyseed strikes a good balance between advanced venting and straightforward cleaning.

5. Size, Ergonomics & Practical Use

5.1 Bottle Sizes

The Thyseed PPSU Anti‑colic bottle is available in:

• 160 ml – ideal for newborns and young infants
• 240 ml – suitable for older babies with larger feeds

5.2 Shape & Handling

While the product text focuses primarily on function, the images show a gently contoured, wide‑neck bottle. This kind of design typically feels comfortable in adult hands during longer feeds and helps caregivers maintain a stable hold. The vented base does not appear to add excessive bulk.

6. Price & Value for Money

At $39.00, Thyseed sits in the mid to premium tier of baby bottles. When evaluating value, consider what you are paying for:

• Premium PPSU material (BASF Ultrason®)
• An integrated anti‑colic base vent
• A breastfeeding‑friendly, wide, soft nipple
• A design that remains dishwasher and sterilizer safe

Verdict on Value: For parents seeking a premium, anti‑colic, breastfeeding‑friendly PPSU bottle, Thyseed offers a solid feature set that justifies its price point.

7. Long‑Term Use & Sustainability

From a long‑term perspective, PPSU is known for withstanding repeated sterilization without becoming cloudy or brittle quickly. Being able to shift from newborn to faster flows means the bottle can stay in use for several months or more.
