NIGHT terrors and Yes. Thank good ness they only lasted a few months. Turn the lights on, a tv cartoon, sing songs, ring a bell..get their attention what ever way you can. I usually wound up picking him up and walking around with him rubbing his back, some nights daddy would too. The look on his face was always terrifying. Scared me. Hang in there. Shouldn't last too long. If it does check with your pedi.
Calm them down and then help them get back to sleep. HUGS.
