Any of you lovely moms of boys have any suggestions for what to do for an almost 15mo old who has been waking up soaked every morning even when wearing a pampers overnight diaper? Usually the last liquid he has is his milk with dinner (about 6:00pm dinner time) and he is usually in bed by 7:30. He wakes up around 7-9am and his jammies are soaking wet. He is wearing a sz4 diaper and I am using sz4 pampers overnights

I am out of ideas at this point and hate the idea of having to set my alarm for halfway through the night to change him and disrupt both our sleep patterns....any ideas????
Thanks a ton!!!
