The concerns over chemicals in plastic baby bottles has led to a relatively new entry in the baby bottle market: stainless steel bottles. These bottles offer an advantage over plastic bottles in that they're made from natural materials. And, unlike glass bottles, you don't have to worry about them shattering when your toddler inevitably drops one or decides to chuck it across the room.
Many of these bottles are also designed for later conversion into sippy cups or water bottles, which gives them a longer lifespan than a traditional baby bottle.
To help you choose a stainless steel baby bottle, here's a list of the top brands to consider:
Made from 18/8 food-grade stainless steel, Kid Kanteen stainless steel baby bottles are free of bisphenol-A (BPA), phthalates, lead and other toxins. They feature a contoured shape that makes them easy for little hands to hold and a wide mouth that makes them easy to fill and clean.
These bottles also feature a medical-grade, silicone nipple designed to more closely simulate breastfeeding because of variations in the nipple's thickness and a wide base measuring more than 2 inches in diameter. The nipple also adjusts as your baby sucks, just like a human breast does as a baby nurses, which helps to promote proper oral development and healthy teeth. The nipple's double venting system also helps to reduce the amount of air your baby swallows, promoting healthy digestion and reducing colic.
These bottles are available in 5- and 9-ounce sizes and the silicone nipples are sold in 2-packs with three different rates of flow. The bottles' interior and exterior both feature embossed and laser-etched marks showing ounces and millimeters. The bottles are also compatible with all Kanteen Wide caps, including their insulated tops. They are 100% recyclable, dishwasher-safe and backed by a lifetime warranty.
These food-grade 18/8 stainless steel bottles are made from a single layer of stainless steel and the lids have a built-in measuring cup. The bottles also have a scale stamped on the side of the bottle that is visible from the outside and inside to assist with measuring.
The single-hulled design means that you can test the temperature of the liquid inside simply by holding the bottle. The bottle will also heat up and cool down more quickly than a plastic or glass bottle. To warm a bottle, simply immerse it in a glass of hot water or use a bottle warmer.
The bottles are free of BPA, polyvinyl chloride (PVC) and phthalates. The nipples come in three flow rates and are compatible with most other major brands.
The bottles are available in 4- or 7-ounce sizes with narrow necks or 4- or 9-ounce sizes with wide necks in a variety of colors. They are 100% recyclable.
These bottles are dishwasher-safe on the top rack, but OrganicKidz recommends hand-washing to prevent the designs from wearing off.
OrganicKidz also makes a 9-ounce thermal baby bottle designed to keep liquids cold or hot for at least 6 hours. For babies who are particular about the temperature of their milk, this makes outings a lot easier, since you don't have to worry about warming up the bottle or keeping it cold. You can also purchase accessories for this bottle to transform it into a sippy cup or water bottle as your child ages.
These bottles are 100% free of plastic and convert to a sippy cup as your child grows. They are independently certified to be free of BPA, phthalates, lead and PVC. Pura says the bottles also do not migrate any heavy metals, including chromium, nickel, cadmium, copper, aluminum, antimony and cobalt.
The bottles feature raised internal volume markings that make it easy to see how much your baby is drinking, and the bottle and its components are dishwasher-safe in the top rack. The bottles are compatible with several other major brands of nipples and spouts. Pura offers three flow rates for its nipples.
Backed by a lifetime warranty on their stainless steel parts, the bottles are available in 5- and 11-ounce sizes in five different colors or natural stainless steel. Pura also offers silicone sleeves available for purchase separately.
Made of food-grade 18/8 stainless steel, these 7-ounce bottles are free of BPA, PVC and phthalates. They come with a slow-flow nipple, sippy top, removable handles and a bottle top, so you can easily transition your child from the bottle to the sippy cup simply by changing accessories.
The sippy tops and nipples also are designed not to drip when turned upside down, helping to reduce mess, and the nipples are available in two rates of flow. The bottle can insulate liquids for at least 4 hours, making it easy to travel with.
This bottle is dishwasher-safe, but Earthlust recommends hand-washing it to preserve the design. The stainless steel bottles are 100% recyclable.
