My ds2 is 4.5 years and is still in pull ups overnight. When he goes to sleep he sleeps like a log and will not wake up even when you try and wake him. I know for a fact he would have a sopping wet bed and wouldn't even notice it just grunt and turn over.
ds1 took longer than him to be dry during day but overnight was a breeze. Although he would wake up if I so much as breathed too heavy in his room.
How do I get the little darling out of pull ups, feel like he will be in em till he is 10.
