A three year old child admitted two days ago with pneumonia becomes incontinent at night. The mother expresses frustration and embarrassment, stating the child has not had a nighttime accident in almost a year. What comment by the LPN to the mother is most appropriate?

1. Don't worry about this. We deal with it all the time.
2. He may have been scared at night because of the noise.
3. We can ask the pediatrician to investigate this issue further.
4. Kids regress temporarily due to the stress of hospitalization.
