Babies who get scared in their sleep! Act of three days! 

If a child or an adult wake up scared from his sleep or he is scared durng the time of his sleep, so for that with ablution recite Durood Sharif three times and after that recite complete surah zilzal 3 times. After reciting the verses, recite the following verses three times and followed by darood shareef thrice. Blow on water.

And give the patient water and sprinkle the same water on the bed. InshaAllah, doing this for three or seven days will remove the fear. That ayat is this:

 وَمَنْ يَّتَوَكَّلْ عَلَى اللّٰهِ فَهُوَ حَسْبُهٗ ۗ اِنَّ اللّٰهَ بَا لِغُ اَمْرِهٖ ۗ قَدْ جَعَلَ اللّٰهُ لِكُلِّ شَيْءٍ قَدْرًا
