Happy Heinys newest product line! The snap setting allows the diaper to grow from small, medium to large. Plus a cross over tab is in place to give the diaper a perfect fit. Two microfiber inserts, one small and one large, come with this diaper to make it complete. This innovative diaper fits babies from birth to potty training (8-35 lbs).
Happy Heiny's One Size Pocket Diapers are available in solid colors. These diapers are tested to last up to 12 hours with absolutely no wicking for most babies. Happy Heiny's One-Size diapers also make great overnight options for heavy wetters. Just take the large microfiber insert and place it on top of a BabyKicks hemp insert, or a Babykicks premium insert and place inside diaper's pocket for a heavy wetter solution. For the super soaker, consider using a Babykicks Hemp Prefold tri-folded as an insert.
The One Size Diapers will still feature milled fleece that keeps baby's bottom nice and dry. New topstitched leg casings provide the very best in mess containment.

*Happy Heiny's recommends drying their diapers on high heat. The high heat of the dryer will keep your Happy Heiny functioning like new. We personally dry Happy Heiny's PUL products on high heat and although we have had prolonged use with these diapers we have not noticed any break down of our PUL.
Washing instructions for Happy Heiny's pocket diapers:
- Remove the inserts
- Cold Soak for 10-20 minutes depending on the level of dirt
- Wash on hot with slightly less than 1/4 cup of detergent
- You can add a downy ball of vinegar to the wash if the diapers have a heavy urine scent. I recommend a downy ball because it releases the vinegar at the right time - no need to wait by the machine.
- Rinse well to ensure all detergent is removed from diapers.
- Dry on high heat. The high heat of the dryer will keep your Happy Heiny functioning like new. We personally dry our PUL products on high heat and although we have had prolonged use with these products we have not noticed any break down of our PUL

What to look for in a Detergent?
At best, a detergent to be used on your baby's diapers would NOT contain enzymes, dyes, perfumes, optical brighteners or any other component designed to be left on your diapers after washing.
Specialty detergents with fabric softeners or wrinkle guards will not be suitable; however, a detergent with non-chlorine bleach or oxygen bleaching capabilities may be fine. And just to be clear, soaps are not detergents, and soaps are generally not suitable for washing diapers.
Top Mainstream Detergent Pick
The top mainstream detergent that we recommend is Tide. Over the years Tide has proven itself to be one of the most stable and readily available detergents on the market. The HE variety for HE machines has been the one detergent that our customers have not reported build up problems with.
Top Environmentally Friendly Detergent Pick
Our favorite top environmental detergent is Country Save. Country Save has no enzymes, brighteners, scents or dyes. Country Save is one of the few environmentally safe detergents that our customers have stated works wonderfully for their heavily soiled work clothes as well. Some other environmentally safe detergents that we recommend are: Allen's Naturally Powder/Liquid Standard & HE compatible, Mountain Green Free & Clear Standard & HE, Mountain Green Free & Clear Baby Standard & HE, Nellie's All Natural Laundry Soda Standard & HE, Planet Ultra Liquid, Planet Ultra Powder Standard & HE compatible and Planet 2X Ultra Standard & HE.
Detergents to avoid:
Natural soaps often contain various oils. These should NOT be used because they will leave a residue on fleece, causing it to repel liquids.
The use of any of these detergents listed below will void the warranty of our products. The use of any free and clear formulas may cause a waxy build up that will cause the diapers to repel and no longer work. We also very specifically do not recommend the use of Sportwash, Sensi-Clean, Charlie’s, due to the possibility of severe burn like reactions that can happen the first time of use or months after successful use. Due to the nature of these detergents the use of them will void all warranties of the Happy Heinys products. The use of chlorine bleach will also void all warranties and can lead to the breakdown of the waterproof layer of our fabric making the diaper unusable.
Avoid: Dr. Bronner’s Soap • 7th Generation • Bio-Kleen • Ivory Snow • Dreft • Charlie’s • Any ALL free detergents • Sport-Wash & Sensi-Clean have the potential for detergent burn in babies.
Never use fabric softener of any kind on reusable diapers. Liquid fabric softeners and dryer sheets both leave a waxy residue which causes fleece to repel urine and decreases the absorbency of other diapers.
