Desmomelts did the thing for DS1, Continence Nurse (horrid title, bless her) did warn us that they do not suit everyone. So success for us, but we didn't go down the bell/mat/alarm road. SO dry by age 8
Trying to think what other things we were told -
Drink loads to stretch the bladder
Avoid orange/blackcurrant/cola-type drinks, milk or water preferable
Don't lift at night, you think the child is awake to pee but they are really half asleep so peeing in their sleep still
Shower in the morning for social reasons - we can all remember going to school ith the smelly child
Make up the bed like this in layers- waterproof, bottom sheet/waterproof, bottom sheet/waterproof, bottom sheet, for whipping off easily in the wee small hours
The eric site is fantastic
