It is generally not recommended to leave a diaper on a baby overnight.
Leaving a diaper on for an extended period, especially overnight, can lead to diaper rash, irritation, and discomfort for the baby.
Babies produce a significant amount of urine and stool during the night, which can accumulate in the diaper and create a breeding ground for bacteria.
Frequent diaper changes, including during the night, help keep the baby's skin clean and dry, reducing the risk of these issues.
If you are concerned about your baby's sleep, consider using a reusable cloth diaper with a waterproof cover. This can help to absorb more moisture and keep the baby drier for longer periods.
However, it is still important to check and change the diaper regularly, even with reusable diapers.
