DS has always been a great sleeper, but just recently he's started acting like he's scared in his crib. If DH or I go in to his room, he calms down, and he's able to fall asleep if we're next to him on the floor beside his crib. Nothing in his room has changed, and he hasn't watched anything scary that would cause this.

I'm wondering what anyone who has been in this situation has done - last night, each time he woke up in the middle of the night, rather than fall back asleep like he normally does, he got scared again and started crying.

Any amazing secrets to solving this one? Thanks!!
