Feeding Bottles: Types, Materials & What to Look For
Baby bottles India stockists carry three main materials: glass, BPA-free polypropylene plastic, and silicone. Each has real trade-offs.
- Glass: Durable, long-lasting, and easy to sterilise. It does not leach chemicals into feeds but is heavier, more expensive, and can break if dropped.
- BPA-free plastic: Lightweight, affordable, and widely available. However, it can become scratched or cloudy over time and should be replaced if damaged or according to the manufacturer's recommendations.
- Silicone: Soft, flexible, and shatter-resistant. It is free from BPA and other harmful chemicals but is generally more expensive and may retain odours over time.
For newborns, glass or food-grade silicone are generally the safest choices. BPA-free plastic is acceptable, but replace bottles at the first sign of scratching or cloudiness. Avoid any bottle not clearly labelled BPA-free.
Nipple Flow Rates by Age
Nipples are graded by flow rate. The wrong rate can cause choking, overfeeding, or frustration.
- Slow flow (Stage 1): newborns up to about 3 months
- Medium flow (Stage 2): roughly 3 to 6 months
- Fast flow (Stage 3): 6 months and above
Variable-flow or Y-cut: thickened feeds when prescribed by a doctor
The recommended stage varies between manufacturers, so choose the flow rate based on your baby's feeding ability and the manufacturer's guidance rather than age alone.
Anti-Colic Features
Many bottles include venting systems that reduce air swallowed during feeds, such as a vented nipple base or an internal straw vent. These can ease post-feed discomfort, though results vary from baby to baby.
