1. Possesses appropriate suction power;
2. Does not cause nipple pain during use;
3. Allows for fine adjustment of suction pressure.
Generally, an infant's sucking pressure is 60-100 mmHg. However, since breastfeeding involves more than just pulling the nipple, simply choosing a breast pump with strong suction isn't sufficient.
Selection Criteria
Choosing the right breast pump depends on how frequently you plan to use it and how much time you can dedicate to pumping. If you work full-time and need to squeeze in time to pump during your workday, you'll need a fully automatic breast pump, as it can express milk from both breasts simultaneously. However, if you only occasionally need to express milk so that someone else can help feed your baby when you're out, an inexpensive manual breast pump will suffice. If you frequently travel or are short on time, a wearable breast pump is a good option.
