I need extra absorbency for night time so I do a triple layer of SAP diapers and a cloth P/U with plastic pants.
1st I open a Tranquility ATN diaper and lay it on the bed.
I cut the elastic off the leg opening from a Parent's Choice size 6 night time toddler diaper, then I cut most of the plastic back off to allow soak through wetness. These are from Walmart.
I do the same with an Equate adult night time pull up brief so it's also a soak through diaper. These are from Walmart.
I lay the Equate brief in the ATN, then I lay the toddler diaper in the Equate one. Now I have 3 layers of SAP products. The toddler diaper soaks the fastest so it's on top. The Equate provides fuller coverage and will soak up a lot. I put on a cloth pull up adult training pants style diaper over the SAP diapers because the SAP's will sometimes leak out of the top or leg openings on a Very heavy flow night, I have a blue and white pull up and an orange and white pull up. Lastly I put on a pair of high back plastic pants.
During a heavy flow night the sides leak out and into the ATN which is there for both soak through and also side and top leakage from the 1st 2 SAP's. Typically the ATN is only damp a little each morning so I can use it usually 2 more nights before it's saturated by layering in a new set of the soak through's above. When the ATN is saturated, I turn the ATN around because the back has been dry, now I layer in the set of soak through's and I get 1 to 2 uses again by using the back as the front of the diaper. This way I can use the ATN up to 5 nights of wetting. It is cold in back for about 20 minutes until it warms up to body temperature.
Then I put on a nice cotton night dress and I'm comfy and ready for bed.
This lets me stretch my diaper funds out as best as I can and there's never any bedding to wash, only a cloth pull up once in a while.
