Night dryness is the last potty training step to develop. There is a hormone known as antidiuretic hormone (ADH) that needs to be produced in order to slow the production of urine during evening sleep cycles. Most children have sufficient ADH to control nighttime bedwetting between ages 2.5 and 4 but it is perfectly normal not to have sufficient ADH until age 7. If your child is under 7, there’s nothing you can do except allow them to wear a nighttime pull-up or use washable sleep pads. Above all, remain positive and do not shame your child. They'll get it eventually.
