How to Use the Natursutten Glass Bottle with Natural Rubber Nipples: A Feeding Guide for New Parents

Quick Answer

To use the Natursutten glass bottle, start by sterilizing the bottle and natural rubber nipple, then assemble them according to the included instructions. Feed your baby using a paced, upright position, and always inspect the nipple for wear before each use. Clean and sterilize after every feeding, and replace the nipple at the first sign of damage.

Feeding your newborn is one of the most frequent and intimate tasks of early parenthood, and the bottle you choose can make a big difference. The Natursutten glass bottle with natural rubber nipples is designed to feel closer to breastfeeding, using materials that are free from BPA, phthalates, polycarbonates, and PVC. But like any feeding tool, it works best when you know how to assemble, use, and care for it properly.

This guide walks you through the entire process, from first sterilization to everyday feeding and long-term care. You'll also learn what to watch for so your baby stays comfortable and safe, whether you're new to bottle feeding or switching from another brand.

Why Choose a Glass Bottle with Natural Rubber Nipples?

Glass bottles have a reputation for being durable and free of the chemicals sometimes found in plastics. The Natursutten bottle is made from borosilicate glass, which is known for its resistance to thermal shock and its eco-friendly profile. For parents who prefer to avoid plastic altogether, this is a clear advantage.

The natural rubber nipple, made in Italy, is ultra-soft and designed to mimic the feel of breastfeeding. This can help ease the transition between breast and bottle, especially for newborns who are still learning to latch. Keep in mind that natural rubber has a distinct scent and a shorter lifespan than silicone, so you'll need to inspect it regularly and replace it when it shows signs of wear.

• Check the nipple for stickiness, discoloration, or tears before each feeding.
• Natural rubber nipples may need replacement more often than silicone ones.

Before First Use: Cleaning and Sterilization

Before you use your Natursutten bottle for the first time, wash all parts in warm, soapy water. Use a gentle brush to clean the inside of the bottle and the nipple, making sure no milk residue remains. Rinse thoroughly.

For sterilization, you can use a steam sterilizer, boiling water, or a cold-water sterilizing solution. If you boil, place the bottle and nipple in a pot of boiling water for about 5 minutes, then let them air-dry on a clean towel. Avoid using harsh chemicals or abrasive scrubbers that could damage the natural rubber.

• Always let the bottle and nipple cool completely before handling.
• Do not use a microwave sterilizer unless the manufacturer explicitly states it is safe.

Assembling the Bottle Correctly

Proper assembly prevents leaks and ensures your baby gets a steady flow. Start by placing the natural rubber nipple into the collar, making sure it sits evenly and is not twisted. Then screw the collar onto the glass bottle until it is snug but not overly tight.

Check that the nipple is aligned with the bottle's neck and that the collar threads are clean. If the nipple is not seated properly, milk can leak or the flow may be too fast. Always do a quick test by turning the bottle upside down – a few drops should come out, not a stream.

• If milk streams out, the nipple may be too loose or the hole too large.
• Replace the collar if it becomes cracked or warped.

Feeding Your Baby with the Natursutten Bottle

Hold your baby in a semi-upright position, supporting their head and neck. Tilt the bottle so the nipple is filled with milk, not air. Let your baby latch onto the nipple naturally, and allow them to suck at their own pace.

Paced feeding – where you let the baby take breaks and control the flow – can help prevent overfeeding and reduce gas. Stop every few minutes to burp your baby, especially if they seem fussy or are swallowing air. Never prop the bottle or leave your baby unattended while feeding.

• Watch for cues that your baby is full, such as turning away or slowing down.
• If your baby is very gassy, try a slower flow nipple or more frequent burping.

Cleaning and Storing After Each Use

After feeding, rinse the bottle and nipple immediately with cool water to remove milk residue. Wash with warm, soapy water and a bottle brush, paying special attention to the nipple's small hole. Rinse thoroughly and allow to air-dry on a clean rack.

You can sterilize again before the next use, but daily sterilization is not always necessary once your baby is older. Store the bottle and nipple in a clean, dry place away from direct sunlight. Sunlight can degrade natural rubber over time.

• Replace the natural rubber nipple every 4-6 weeks or at the first sign of wear.
• Do not use a dishwasher for the nipple unless the manufacturer states it is safe.

Step-by-Step Feeding Routine

1. Sterilize all parts: Before first use and after every feeding, sterilize the bottle and nipple using boiling water, steam, or a cold-water solution. Let them cool and dry completely. Checkpoint: Ensure no water droplets remain inside the nipple before assembly.
2. Assemble the bottle: Fit the nipple into the collar, ensuring it is centered and not twisted. Screw the collar onto the glass bottle until snug. Checkpoint: Turn the bottle upside down – a few drops should come out, not a stream.
3. Warm the milk (optional): If warming, place the filled bottle in a bowl of warm water for a few minutes. Do not use a microwave, as it can create hot spots and damage the nipple. Shake well and test the temperature on your wrist before feeding.
4. Feed in a paced, upright position: Hold your baby semi-upright, tilt the bottle so the nipple is full of milk, and let your baby control the pace. Burp frequently. Watch for fullness cues and stop when your baby turns away or slows down.
5. Clean and inspect after feeding: Rinse immediately, wash with soap and water, and air-dry. Inspect the nipple for wear or damage. Replace the nipple at the first sign of stickiness, tears, or discoloration.
