poor baby

It is eleven at night already and my daughter Bella still awake. He took a nap this afternoon and woke up around seven pm. Now she still awake and crying. She do not want to go back to sleep yet. I just put her pajama on. Asked her to go to the bathroom to pee but she said she do not want to. My husband told me today that she peed on her bed, so he washed all her bed sheets.  When I asked her to go pee she cries. I do not know what to do. I do not want her to have an accident again on her bed. I know that she is tired already,  and do not want to get up from bed. She is asking for milk and I said no. She is not hungry. She just could not go back to sleep. Poor baby!
