Hotchner- If he had a nightmare you will lay him on your chest and sing him to sleep. He will make you some tea and hold you as you tell him what happened.
Rossi- Both of you do the same thing just hold the one that had the nightmare,and if they want to talk about it you listen.
Reid- If he has a nightmare you pull him close and play with his hair till he falls asleep. If you have a nightmare he pulls you close and reads to you.
Morgan- When he has nightmares you make some tea and turn Netflix on,with his cuddling you close. You rarely have nightmares but when you do he pulls you close and whispers sweet nothing's in your ear until your fast asleep.
