ds1, just turned 3 and ghas been dry every night since (barr one or 2 were he was sick)
however
ds2, is 4 in june and still has to have a night nappy, he has the odd night were he will be dry, but it is very very rare, ive tried just leaving him hoping he would 'click' to being wet, even getting up and getting him to go during the night, but nothing! so for my own sanity he has pull ups at night, or im doing daily loads of sheets!
