DD is 4 and a half months. She used to be good at night but has always been terrible at sleeping in the day. We've been trying to get her in a routine... She won't have any of it. We've been trying to get her to self settle...again she's not having it. Now she's started getting up at 4 or 5 am every day and despite my best efforts won't have a proper sleep in the day, maybe half an hour at best maybe 2 or 3 times a day. I'm going out of my mind and don't know what to do!!!!
