I just have to chime in to, again, say that it's perfectly normal for a 4 yr. old to still be wet at night. My older kids were all at least 8 before they were dry at night. My 9 year old daughter is still wearing pull-ups and there is not a single night that she's dry. I assume my toddler will be the same way. The kids really cannot help it. Sure, there may be some kids who just don't want to get out of bed to go and pee in their pull-up ( we had that issue with my daughter at one point and she got grounded). BUT, during the night, when she sleeps, she cannot wake to go. My kids sleep SO HARD, their bodies just don't hear the "Wake up- you have to pee" signal. They sleep through fire alarms, house alarms, storms, dogs, etc. Your daughter may just be one of those kids who take longer. No worries.
