I would quickly return them back to bed no fuss or talking, it does require you to get up off the couch for a few nights but I found they soon get tired of not getting a response. Keep the same routine every night. My DD didn't like going to bed and would call out from her bed because she new that she had to stay there. Things that helped were having just one cuddly toy, a night light and shutting her cupboard doors because she was scared if they were open. Good luck
