From pump-action bottles and soft plastic tubes to powders, balms, and glass jars, baby products come in all shapes and sensitivities. Many are fragile. Some are messy. And others can be outright destructive if damaged in transit.

For baby brands, a cracked cap or leaked cream isn’t just a packaging failure—it’s a broken promise. Customers in this category expect safety, cleanliness, and care. When they open a box and find a mess, trust evaporates—making the right fulfillment setup essential to brand success.

In this post—part of our series on best practices for baby products fulfillment—we explore how to properly protect fragile, irregular, and leak-prone items from warehouse to doorstep.

Why Baby Products Pose Unique Fulfillment Risks

Compared to many consumer categories, baby products are unusually diverse in form and structure—and often more vulnerable to mishandling.

These are the stakes:

  • Unusual shapes and weights: Glass bottles, pump dispensers, squeeze tubes, and soft pouches don’t stack neatly. They require careful orientation and individualized protection.
  • Leak potential: Liquids and creams can seep through seals or burst open under pressure—especially during summer heat or winter freeze-thaw cycles.
  • Pressure sensitivity: Thin plastics, partially filled containers, and air-tight lids can expand, collapse, or crack depending on temperature and altitude changes in transit.
  • Immediate emotional impact: Parents aren’t just annoyed by damage—they’re disgusted. A soiled item or sticky box creates instant brand aversion, even if the damage wasn’t your fault.

In baby fulfillment, protection isn’t optional—it’s the baseline for being taken seriously.

Product-Specific Protection Starts at the Warehouse

Preventing leaks and breakage begins before an order is ever packed. Proper storage, orientation, and handling protocols reduce risk and improve consistency.

Your operation must embrace the following realities:

  • Upright storage matters: Pump-action bottles and tubes must be stored upright—not laid flat—to reduce pressure on seals and prevent slow leaks over time.
  • Temperature-aware handling is essential: Products like diaper cream, probiotics, or liquid vitamins can degrade in heat or cold. Fulfillment teams must understand how ambient temperatures affect storage and shipping stability.
  • Pre-screening for weak packaging: Some vendor-supplied items arrive with inadequate seals or fragile materials. Flagging and separating these helps prevent a bad batch from reaching customers.
  • Non-slip organization: Irregular-shaped items (like curved jars or pouches) should be stored in bins or trays that minimize shifting and reduce the risk of breakage during picking.

Warehouse readiness is just as important as final packaging. Protection begins with storage.

Packaging That Prevents Breakage, Leaks, and Complaints

Packaging isn’t just about branding—it’s about physics. The right materials and methods minimize movement, absorb shock, and keep products upright and clean.

Be sure to:

  • Use the right padding for the product: Foam inserts work well for glass or rigid bottles. Crinkle paper or soft wrap works better for tubes and jars. Avoid over-relying on air pillows—they shift too easily.
  • Anchor irregular items: Use snug-fitting cartons, dividers, or molded inserts to prevent bouncing during transit. Loose-fit packaging almost always leads to mess.
  • Double-wrap leak-prone SKUs: Baby shampoo, diaper balm, or supplements should be enclosed in a sealed pouch or plastic bag inside the main packaging—so even if something leaks, the rest of the order is protected.
  • Test packouts by SKU type: Run test shipments with your 3PL or in-house team for any items that routinely leak, crush, or dent. Small tweaks (like capping orientation or added liner) can prevent major issues.

The goal is to make sure what arrives in a customer’s hands is exactly what they expected—clean, safe, and ready to use.

Watching for Patterns—and Acting on Them

Even with strong protocols in place, issues can happen. The key is to track them, learn from them, and prevent repeat mistakes.

Be proactive about:

  • Flagging damage-prone SKUs: If certain products regularly leak, crack, or scuff—redesign packaging or add additional safeguards.
  • Tracking damage by carrier or region: Certain routes or services may handle items more roughly. Avoid budget shipping options for fragile or heat-sensitive items.
  • Reviewing customer service reports: Feedback around leaks, mess, or broken seals should feed directly into packaging and fulfillment improvement cycles.
  • Notifying suppliers of recurring issues: If product packaging fails too often, the issue may originate upstream. Better seals or stronger containers may be needed at the manufacturing level.

Mistakes are inevitable. Repeating them isn’t. Fulfillment operations must evolve based on real-world outcomes.

Clean Deliveries Build Customer Confidence

Parents order baby products expecting trust, quality, and peace of mind. A clean, intact delivery reinforces those expectations. A sticky, broken, or leaking one violates them.

Protecting fragile, irregular, or leak-prone items isn’t about perfection—it’s about care. The right fulfillment process anticipates where things go wrong and builds systems to prevent them.
