Starting your cloth diaper journey can feel overwhelming, especially when you encounter terms like inserts, boosters, and absorbency. But don't worry—this guide will break down everything you need to know about cloth diaper inserts and how to achieve the perfect absorbency for your baby. Whether you're a first-time parent or looking to optimize your current stash, understanding the different materials and configurations will save you time, money, and frustration.
At Squishy Lil' Campers, we believe that cloth diapering should be simple and effective. That's why we offer a range of products designed to meet your baby's unique needs. Let's dive into the world of cloth diaper inserts and discover how to keep your little one dry and comfortable.
Why Absorbency Matters in Cloth Diapering
Absorbency is the cornerstone of a successful cloth diaper system. If your diaper doesn't absorb enough, you'll face leaks, wet clothes, and a fussy baby. On the other hand, too much absorbency can lead to bulkiness and discomfort. The key is finding the right balance for your baby's age, urine output, and activity level.
Newborns typically need less absorbency because they pee frequently but in small amounts. As your baby grows, their bladder capacity increases, and they may go longer between changes. Heavy wetters, especially at night, require extra absorbency to stay dry for extended periods. Understanding these patterns will help you choose the right inserts and adjust your stuffing as needed.
- Start with a basic insert and add boosters for heavy wetting.
- Test absorbency by doing a simple 'squeeze test' after washing.
Types of Cloth Diaper Inserts
Cloth diaper inserts come in various materials, each with its own absorbency characteristics. The most common types include microfiber, cotton, hemp, and bamboo. Microfiber inserts are quick-absorbing but can be prone to compression leaks. Cotton inserts are natural, durable, and absorb slowly but hold a lot. Hemp inserts are highly absorbent and great for heavy wetters, while bamboo blends offer a soft, eco-friendly option with excellent absorbency.
Many parents start with a mix of materials to cover different situations. For example, you might use a microfiber insert for daytime changes and a hemp or bamboo booster for naps or overnight. At Squishy Lil' Campers, we offer versatile options like the Farmers Market-OS-In stock, which pairs well with various inserts to customize absorbency.

- Microfiber: fast absorption, affordable, but prone to compression leaks.
- Cotton: natural, durable, good for daytime use.
- Hemp: very absorbent, slow to absorb, ideal for heavy wetters.
- Bamboo: soft, eco-friendly, great for sensitive skin.
How to Stuff Your Pocket Diapers for Optimal Absorbency
Pocket diapers are popular because they allow you to customize absorbency by choosing which inserts to stuff inside. The general rule is to use one insert for daytime and two for naps or overnight. For heavy wetters, consider layering a microfiber insert on top of a natural fiber insert like hemp or cotton. This combo gives you quick absorption on top and long-lasting absorbency below.
When stuffing, ensure the insert lies flat inside the pocket to avoid bunching. You can also trifold an insert and lay it on top of the pocket for easier changes. For example, the Snackin-OS Pocket is a great choice for experimenting with different stuffing configurations. Remember to adjust as your baby grows—what works at 3 months may not be enough at 9 months.

- Layer a microfiber insert on top of a hemp or cotton insert for heavy wetting.
- Trifold an insert and lay it on top of the pocket for quick changes.
- Test different combinations to find what works best for your baby.
Boosters and Doublers: When and How to Use Them
Boosters and doublers are extra absorbency layers that you can add to any diaper system. They are especially useful for overnight diapering or for babies who are heavy wetters. Boosters are typically smaller and designed to be placed inside a pocket or on top of a prefold. Doublers are larger and can be used to add absorbency to flats or fitteds.
You can use a booster with a pocket diaper like the Don’t Be A Karen-OS Pocket to extend its wear time. Simply place the booster inside the pocket or lay it on top of the insert. For overnight, consider using a hemp or bamboo booster for maximum absorbency without excessive bulk.
- Use boosters for naps, car rides, or overnight.
- Choose hemp or bamboo boosters for heavy wetting.
- Avoid over-stuffing—too much bulk can cause gaps and leaks.
Caring for Your Inserts to Maintain Absorbency
Proper care is essential to keep your inserts performing at their best. Over time, detergent buildup, hard water minerals, and bacteria can reduce absorbency. To prevent this, wash your inserts in hot water with a cloth-diaper-safe detergent. Avoid fabric softeners and dryer sheets, as they coat the fibers and repel liquid.
Every few months, do a strip wash to remove buildup. You can also test absorbency by dropping water on a clean insert—if it beads up, it's time to strip. For natural fibers like hemp and cotton, occasional sunning can help whiten and refresh them. With proper care, your inserts will last through multiple children.
- Wash inserts in hot water with a cloth-diaper-safe detergent.
- Avoid fabric softeners and dryer sheets.
- Strip inserts every 3-6 months to remove buildup.
- Sun-dry natural fiber inserts to keep them fresh.
Mastering cloth diaper inserts and absorbency is a game-changer for any cloth diapering parent. With the right combination of materials and stuffing techniques, you can keep your baby dry and comfortable all day and night. Ready to build your perfect stash?
