Gosh I'm so out of practice when it comes to these things! I didn't even think to watch the child's water intake at lunch to see if that might help. The accidents aren't regular, they occur about once every two weeks. It's not a large amount, just enough to soak through the clothes and sheet . I didn't know they had pads, i'll check into those. The parents sent the child in pull ups this morning and I felt so bad because the child doesn't need to wear pull ups all day just quiet time. The only downfall is I'm so used to the child not wearing pull ups that I forget.
The last two days that the child has had an accident I have noticed that she was sleeping very soundly and hard to wake up, so I agree that might be some of the cause. So the pads seem to be a better option than pull ups.
