Trying to figure out how to choose a more sustainable and non-toxic baby bottle? Most baby feeding bottles are made of plastic, glass, tritan, PESU, PPSU or silicone — and each type has its pros and cons as well as what you need to consider when choosing nipples, shape and size! Which bottles are best for you will depend on your baby, your family’s lifestyle and how to plan to use them.
Baby bottle shapes, sizes and other options
Once you’ve decided on the material, there a few other options to consider:
- Disposable inserts: Some plastic bottles can be used with disposable sterilized liners that are thrown away after each feeding. They’re convenient because they cut down on cleaning time, but they’re expensive and bad for the environment.
- Bottle shape: Baby bottles come in a variety of shapes that have different advantages. Standard bottles are straight-necked and fit into most bottle warmers and cupholders. Angled bottles have a curved neck that reduces the amount of air your baby swallows. Wide-neck bottles have wider nipples that mimic human ones and can help reduce nipple confusion in breastfed babies.
- Venting: Different types of venting systems help minimize air bubbles that can cause painful gas. If your baby seems fidgety or cries after feeding, a vented bottle may help.
- Size: Small bottles hold 4 or 5 ounces, while large bottles can hold between 8 and 10 ounces. Start with small bottles and switch to bigger ones around four months or whenever your baby’s appetite increases.
