I am at the end of tether! 18 month old has for the last few weeks been waking really early. He used to sleep until 7:30 no problem but now I have unbroken sleep from 4 onwards, every 1/2 hour I go in to him to resettle or give a dummy/ bottle. This morning was from 4:30am. And eventually I get up and feel really cross with ds which isn't fair. Please someone have a magic trick! I can't function during the day :-(
