Daytime, and Night-time pottying, are 2 entirely different things.
Per night time, it has to do with BIOLOGICAL maturity of the organs/nerve connections/brain/bladder.
Nigh-Time dryness, is NOT something that is attained, until even 7 years old... and is NORMAL and per Pediatricians.
Sleep deprivation, because a child is woken up during the night to potty, is worse, than wetting a bed.
Because, at this stage of bladder/body development, a night time diaper, is still used and needed.
AND get a waterproof bed pad to put under him, so that clean up is lots easier.
My son is 5. He is still wet at night. Normal. He wears night time diapers.
My daughter was 5 and still in night time diapers too.
UNTIL she was even 7 years old, she STILL had night time accidents.
Normal.
PER our Pediatrician as well.
AND per ALL of my daughter's Teachers, from Preschool to Kindergarten to 1st Grade.... pee accidents, whether day or night... is normal and happens at these ages. And night time diapers.
My kids, NEVER EVER EVER, got "confused" about wearing a diaper at night, and only at night. They understood. Because I explained to them... that their body is not ready yet, to be dry. Thus a diaper is needed. Until their body, grows up.
Night Time Dryness... is completely DIFFERENT and on a different timeline... than day time pottying.
It is NOT, the same.
Night time dryness... is all about PHYSIOLOGICAL maturity and development of the organs.
Your son is SO young.
Waking a child at night just to pee and/or limiting their liquid intake at night, is only artificially, making them pee or not.
It is not, their body development to do so. It is not natural.
