Night Terrors

Thus far in my adventures of motherhood I think one of the worst moments for me is when my son has night terrors. At least I think they are night terrors. He has horrible dreams and sits up screaming and crying inconsolably. When I go into his room to try to comfort him he is not cognitive at all. I feel helpless and he seems so terrified. It goes on for ten minutes sometimes. I just hold him and run my fingers through his hair hoping it helps.
