These sized inserts conveniently snap into the Best Bottom One-Size diaper cover.  Simply choose the best size for your baby, and then select the preferred fabric from stay-dry (with microfiber backing) or hemp/organic cotton and then select a few microboosters and overnight boosters for times when baby needs more absorption.  Depending on your baby's age and habits, you will need approximately 18-24 inserts per size to make a full set for 2-3 days between washing.  It is likely that you will need more inserts when baby is younger and fewer as baby grows and has fewer bowel movements (pad absorbency increases with size).

Sizing is approximate and will depend on baby's shape, size and urine output.

Small: birth-14lbs, Medium: 11-22lbs, Large: 16-35lbs.

• Stay Dry Insert consists of 4 layers of super thirsty microfiber topped with a super soft no-pill fleece pulling wetness away from baby's bottom keeping them feeling dry.

• Hemp/Organic Cotton Insert consists of 5 layers of hemp/Certified Organic cotton topped with a soft layer of hemp/Certified Organic cotton fleece. This insert is so trim you will be able to have your baby wear jeans again! Please note that hemp inserts will shrink slightly during first washings making them consistent with the other insert sizing.

• Overnight Insert: Micro Overnight Insert consists of 6 layers of super thirsty microfiber made to fit with any Regular insert option of the same size. Snap overnight insert into cover then snap regular insert of your choice on top.
  

• Hemp/Organic Cotton Overnight: Insert consists of Hemp/Certified Organic cotton topped with a soft layer of hemp/Certified Organic cotton fleece. Snap overnight insert into cover then snap regular insert of your choice on top.

• Micro Doubler:  Perfect for heavy wetters, long car rides, or long naps! Each Micro Doubler has 2 layers of thirsty microfiber and is made to fit with any regular insert of the same size. To use, snap in the Micro Doubler and then snap a regular insert of your choice on top.

How Does The Best Bottom System Work:

1. Adjust front snaps to achieve the size needed.
2. Snap insert into diaper.
3. Put diaper on baby and go!
4. When baby needs a diaper change snap out soiled insert and snap clean one in.
5. Put diaper on baby and go AGAIN. The Best Bottom shell is wipe-able and can be used multiple times before washing but you may want to air dry between uses but it is not necessary.

We recommend getting as many shells as your baby poos in a 2-3 day time period (for newborns count how many explosions they have!!). We have found that poo does stay on the insert most of the time but in some cases it may not (but it will stay in the diaper cover avoiding an embarassing mess!) Three different size inserts in several different materials available. We don't believe in a one size insert. Newborns and toddlers are not the same size so in order for a one size insert to absorb enough for a toddler it will be HUGE on a newborn. Y ou may not need all three sizes of inserts and can skip the middle size - it is all up to you! We recommend approximately 24 inserts per size.

So to make it SIMPLE you will need approx 8-10 shells and 18-24 inserts per size. How easy is that?!
