Question: Why do they appear extra small? How can I expect them to fit my child for more than a year? This answer is simple. High quality swim diapers are nothing like regular cloth diapers! They need to be smaller! Here are several reasons why they need to be smaller + they will fit your child up to 36 lbs if you fit them right. Firstly they are immersed into water. This means the seal on the legs and the waist is super important to be firm fitting. If not it will not contain a poop when it arrives and poo particles will be flushed out the legs along with the existing water 2) Secondly they are not meant to hold wee therefore a good swim diaper won't contain any padding like Huggies or Pampers Splashers. If it contains padding it will become heavy and pull down on the leg seals and cause a poo leak 3) It's all about the fitting. Our stretchy edging is so comfortable it is specifically designed to be pulled and secured firmly and be comfortable for the infant while creating a good seal to prevent water entering and poop leaking. If the diaper is designed any larger it will not serve its purpose for all children that are in their diaper years. We think 36lbs is plenty large enough as most children are potty trained by this stage. If it is any larger in size it will not work effectively for their first years. Another important note is most children are at their chunkiest around the 1 year old / 18 months. Once they start running around and becoming active your baby girl or boy will lean out and increase in height for the next couple of years! Our diaper works perfectly to adapt to this growth.
