FAQ
Will sleep training fail if my baby's diaper leaks at night?
Likely yes - nighttime leaks teach baby to wake. Cuddle Kin's 12hr bamboo diapers remove that variable.
Should I size up overnight?
Yes - size up by one for more absorbency room and quieter fit.
How long does sleep training usually take with reliable overnight diapers?
3-7 nights for most methods, 7-14 for gentler approaches.
Bamboo vs plastic for night?
Bamboo runs 4-6°F cooler - prevents heat-wakeups too. Full Cuddle Kin range.
Subscription save how much?15% standard - cuts night-diaper budget about 1/6.
