I hope you can help. My 16 month old DD has woken up for the past week at about midnight really crying and then not going back to sleep for at least a few hours. We have tried cuddling her (which usually works and then she will go straight back to sleep) letting her crying it out (lasted for an hour last night) calpol, bonjela, water, changing her nappy and none of this seems to work. The only thing that has worked is bringing her in to bed which I really try to avoid doing but when we both have to work the next day and still awake at 3am will try anything! Any ideas what it might be? Am sure it's probably teething again but not sure how to handle the situation and now very, very tired! Thank you.
