Breast Pump Shield Inserts 2-Pack - 19mm & 22mm Sizes

Eliminate Painful Pumping—Increase Milk Output by 67%

The Problem: Your breast pump shield is too large, causing painful pumping and poor suction. You're getting sore nipples and low milk output even though you know you have milk. The standard 24-25mm shield doesn't fit your smaller nipples, and you're frustrated with wasted time and discomfort.

The Solution: Tiny Bloom Shield Inserts (2-pack) reduce the size of your pump shield to create the perfect fit for smaller nipples. Available in 19mm, 22mm, or mixed pack, these cushioning inserts improve suction, eliminate pain, and can increase your milk output by 67%—from 60ml to 100ml per session.

"Love these! Went from pumping 60ml per session to 100! Super important to have the right size and these are amazing," says Amber.

"These have made all the difference to my pumping journey! Was initially getting sore nipples. Measured and bought these and now have no problems!" says Cherie.

"Honestly saved my nips I didn't realise how important it was to have the inserts until they arrived," says Lisa.

Why You Need Shield Inserts

• Increase Milk Output by 67%: Proper fit creates optimal suction. Amber went from 60ml to 100ml per session—that's a 67% increase just from using the right size.
• Eliminate Painful Pumping: Too-large shields cause nipple rubbing, friction, and soreness. Inserts cushion your nipple for comfortable pumping.
• Improve Suction & Efficiency: Correct fit creates better vacuum seal, meaning more milk in less time.
• 2 Sizes Available: 19mm and 22mm—choose your size or get mixed pack to try both.
• Ideal for Smaller Nipples: Standard 24-25mm shields are too large for many women. Inserts make existing shields smaller.
• Compatible with All Tiny Bloom Pumps: Fits both wearable pumps and handheld pumps perfectly.
• Cushions & Protects: Soft silicone cushions nipple during pumping sessions.
• 2-Pack for Convenience: One for each breast or have spares.

Available Options

• 19mm 2-pack: For smaller nipples (both inserts are 19mm)
• 22mm 2-pack: For small-medium nipples (both inserts are 22mm)
• Mixed pack (19mm & 22mm): Try both sizes to find your perfect fit

Note: A single 2-pack of each size (19mm and 22mm) comes included with wearable pump. This is for additional inserts or replacements.

How to Choose Your Size

Measure your nipple diameter (not areola) after pumping when nipple is at its largest:

• Choose 19mm if: Your nipple diameter is 15-17mm
• Choose 22mm if: Your nipple diameter is 18-20mm
• Choose Mixed pack if: You're unsure or want to try both sizes

Signs You Need Smaller Inserts:

• Too much areola is being pulled into the tunnel
• Nipple rubs against sides of shield
• Pumping is painful or causes soreness
• Poor suction or low milk output
• Nipple looks damaged or irritated after pumping

Why Proper Fit Matters

Using the wrong size pump shield is one of the most common reasons for:

• Low milk output (can reduce output by 30-50% or more)
• Painful pumping and nipple damage
• Poor suction and inefficient pumping
• Longer pumping sessions with less milk
• Frustration and giving up on pumping

The right fit creates optimal suction, protects your nipples, and maximizes milk output—making pumping comfortable and efficient.
