Does your child still pee / poo in the night time diapers? When I discovered my child does not pee / poo in her night time diapers for consecutively 1 week, I decide to let her go diaper free (she is already well trained for day time). During that period of time, I will asked her if i can let her go without diapers for that night, to which she readily agreed. I will also remind her to wake me up should she wish to pee / poo.
Initially, there was a little leak on 1 or 2 occasions. But now, she will wake me up whenever she wants to pee / poo
I will also bring her to the toilet just before she sleep.
Hope that helps
