Deciding between a small or xlarge cloth diaper trial kit? Our guide compares sizes and contents so you can pick the right starter kit for your baby.
Quick Answer
Start with a small kit if your baby is under 14 pounds and you want to test both prefolds and fitted diapers; choose an xlarge kit if your toddler is 28–35 pounds and you're ready for a full set.
Match the Kit to Your Baby's Weight, Not Age
Cloth diaper sizes are based on weight, not age. A small kit fits about 9 to 14 pounds, while an xlarge kit fits about 28 to 35 pounds. If your baby is between sizes or you're unsure, check the weight ranges first—this is the most reliable way to avoid buying diapers that won't fit.
Prefolds vs. Fitted Diapers: Why Try Both?
Prefolds are versatile and budget-friendly; fitted diapers are easier to put on and often more absorbent. Trying both in one kit lets you see which style you prefer before committing to a full stash. Both the small and xlarge Try Both Kits include six prefolds and six fitted diapers, so you get a real comparison without buying two separate sets.
What's Included: Small vs. XLarge
The small Try Both Kit includes 12 diaper changes: six small prefolds, six small fitted diapers, three Thirsties Duo Wrap covers, and a pair of GMD Slide Lock Pins. The xlarge Try Both Kit includes six large prefolds, six xlarge Workhorse diapers, two Thirsties covers, and three doublers plus a triple pack of Snappi Fasteners. The xlarge kit also includes doublers, which are useful for older babies who need extra absorbency at night.
Decision Rules for Choosing a Trial Kit
- Baby weighs 9–14 pounds: Choose the Small Try Both Kit. It gives you 12 diaper changes and includes both prefolds and fitted diapers, plus covers and pins. This is the smallest and most affordable way to test cloth diapering on a newborn.
- Baby weighs 28–35 pounds: Choose the Try Both Kit - XLarge. It includes 6 prefolds, 6 fitted diapers, 2 covers, and doublers for extra absorbency. This kit is designed for toddlers and includes doublers for overnight or heavy wetting.
- Baby is between sizes or you're unsure: If your baby is close to the upper or lower weight limit, consider how quickly they are growing. A small kit may only last a few weeks; an xlarge kit will last longer if your toddler is already at the lower end. If in doubt, choose the larger size if your baby is near the upper limit of the smaller size.
