Just pondering on it, as through a lack of organisation I've run out of nappies tonight for DS3 so he's gone to bed without one.
DS1 is still wet regularly (at 10yrs old - we're getting there now I think)
DS2 was dry at night at 3.5 - can count the number of accidents he's had on one hand since then (he's nearly 7 now(, but had been dry during the day for a year before that
DS3 is also 3.5, and only been trained for about 7 weeks, only reliable in the last 2 or 3
Obviously 3.5yrs is still quite early, so if he's soaked I know it's not a big deal, we just go shopping tomorrow like I should have today 
.
But just really wondering if you've had 1 late to be dry at night, and one within "normal" range which way the 3rd went.........
