1. How to Choose the Right AVENT Products for Your Baby？

1.1. Bottles: Choose based on age, material, and anti-colic features

1.1.1. Capacity and Flow Rate (Most Critical)

0–3 months (Newborns)

Capacity: 120–160 ml (small capacity to avoid waste and choking)

Nipple: 1-hole/2-hole (slow flow), anti-colic dual valve to reduce spitting up and gas

Recommended: Natural Series Glass/PP Small Bottles (SCY930/01)

3–6 months

Capacity: 240–260 ml

Nipple: 3-hole (medium flow), suitable for increased milk intake

Recommended: Nature Series PPSU/Glass Bottles (SCY943/02, SCY933/01)

6 months+

Capacity: 330 ml, available with a handle for easy baby grip

Nipple: 4-hole (fast flow), suitable for solid foods and increased milk intake

Recommended: Nature Series PPSU Large Bottle (SCY946/01)

1.1.2. How to Choose Materials

Glass (Recommended for Newborns): Heat-resistant, easy to clean, odor-free, suitable for frequent sterilization; drawbacks include being heavy and fragile

PPSU (Recommended for 3 months+): Lightweight, shatter-resistant, and heat-resistant; suitable for babies to hold on their own and for on-the-go use

PP: High value for money and lightweight; suitable for everyday home use

1.1.3. Must-Know Tips for Preventing Gas

Prioritize the Natural Series with AirFlex dual valves; during feeding, air is directed to the bottom of the bottle instead of into the baby’s stomach, reducing gas and colic

1.2. Pacifiers: Choose Based on Age and Oral Development

0–3 months: Choose the Soothie all-silicone one-piece design—ultra-soft, lightweight, and gentle on the mouth; same model used in hospitals

3–6 months: Ultra Soft series—flat-tip orthodontic design that does not interfere with gum development

6–18 months: Ultra Air series—lightweight, breathable, and comfortable against the face; ideal for teething

18 months+: Choose orthodontic-style pacifiers with ventilation holes to protect the alignment of baby teeth

1.3. Breast Pumps: Choose Based on Mom’s Needs

Single-Side Electric (SCF397): Great value for money, ideal for working moms pumping at the office or daily use; 4 modes + memory function; petal massage pad for added comfort. Philips

Double Electric (SCF316): Higher efficiency, ideal for moms with abundant milk supply and tight schedules; simultaneous double pumping saves time

Manual (SCF430): Lightweight and quiet, perfect for travel and nighttime emergencies; allows for customizable suction strength

1.4. Training Cups: Choose based on drinking stage

6 months+ (Transition): Soft-spout training cup (SCF600/11): Nipple-like design, easy for babies to accept, leak-proof

12 months+: Magic cup/straw cup (SCF670/01): Gravity ball design, allows babies to drink while sitting or lying down

18 months+: Sports-style straw cup (SCF604/11): Anti-choking, shatter-resistant, ideal for outings and the toddler stage

1.5. General Selection Guidelines

Safety First: Choose products free of BPA/BPS and certified by 3C

Easy to Clean: Wide-mouth design with few parts for easy disassembly, cleaning, and sterilization to prevent dirt buildup

Compatibility: Interchangeable parts across the same product series (bottles/nipples/training cups) save money and hassle

Observe Your Baby’s Reactions: If your baby chokes, becomes fussy, or refuses to drink, adjust the flow rate, capacity, or material promptly

2. When should I increase my baby’s bottle size?

If any two of the following signs appear, it means it’s time to switch to a larger bottle

1. Finishes every feeding but still seems hungry

Finishes each feeding very quickly

Continues sucking on the nipple, cries, or searches for milk after finishing

Note: The milk volume is insufficient; switch to a larger capacity.

2. One bottle isn’t enough; you have to prepare a second one

A single 120ml serving isn’t enough; you need to prepare an additional 30–60ml

Switch directly to a 240ml bottle or larger to avoid having to prepare two servings

3. The bottle is too full, leading to spills or choking during feeding

If you fill a small bottle too much, it overflows as soon as you put the cap on

You must switch to a larger bottle; otherwise, feeding will be a hassle

4. Baby has reached the appropriate age (reference guidelines)

0–3 months: Use 120ml/160ml

3–6 months: Must switch to 240ml/260ml

6 months and older: Use 330ml
