S.H.
Are you talking about night time or day time pottying????
Night time dryness... is NOT the same thing as daytime. And, night time dryness is not something that develops until even 7 years old. AND this is normal.
Night time dryness, has to do with the PHYSIOLOGICAL development of the organs. And you cannot speed up, organ development.
My son is 5 and still needs night time diapers for naps or bedtime.
My daughter even at 7 years old, had night time accidents.
NORMAL.
Using alarms or waking them or punishing them for accidents, does not help. It just results in lack of sleep.
I have waterproof bed pads to put under my kids. The sheets do not get soiled that way. I got mine from Amazon.
Night time dryness is physiological.
ALL kids have accidents.
ALL of my daughter's teachers, from Preschool to Kindergarten to 1st Grade, ALL said, that kids these ages have accidents. Daytime or night time and they wear night time diapers. Their body is not fully developed yet.
It is normal.
