Preparations before pumping

1.Select flange size

The Momcozy wearable breast pump comes with a 24mm flange and 17/19/21mm inserts as standard.If these sizes do not fit, search momcozy on Amazon or Momcozy’s official website to purchase suitable flanges and inserts.

2. Stimulate the nipple

a)Stimulate your nipple to get a fullsize（do not skip this step).

b)Place the nipple into the smallest hole you can comfortably fit into without forcing it.

c)Select the hole that can comfortably fit the very base of your nipple.

d)Get your measurement based on the sizing chart.

3. Test the flange fit

A.To find the suitable size flange,first,you need to make sure you place the flange in the right place on your breast.

B.Please press the flange on your breast until there is no gap. Make sure your nipple is right in the middle of the flange.

Too Small	Too small: During pumping, if your nipple continues to rub against the inner wall of the flange, then this flange is too small for you.
Good Fit	Suitable fitting: During pumping, if your nipple moves smoothly without rubbing or touching the inner wall of the flange, and almost no areola is sucked inside, then this flange is right for you.
Too Large	Too large: During pumping, if a large area of areola is sucked inside, then this flange is too big for you.

4. Get the right bra

• NO GAP：When you put the pump inside your bra, the silicone Flange of this pump should be firmly pressed against your skin without a gap.
• IF IT MOVES：If you feel the pump moves during use, please tighten your bra strap to adjust the pump again, or choose another bra.

5. Recommend posture

• Always pump in an upright sitting or standing position to prevent milk leakage. Do not use the pump while lying down or sleeping, to maintain proper orientation during use.

• Keep the pump and milk collector at a vertical angle at all times; otherwise, milk may spill.
