Has anyone got any ideas - my 6mo DS4 is a good sleeper during the day, he goes down with absolutely no trouble at 7pm but has never slept later than 5 - 5.15am. He wakes like clockwork really crying every day - he doesn't burble a bit then decide he's hungry and start crying iykwim he wakes with a cry. I don't think he's hungry, I've tried leaving him to cry but he just gets worse and worse as if he's in pain. By 6am I normally feed him (bf) and then he'll doze until 7ish when he has the rest of his feed. I go back to work soon and really need some help/ideas to help me to get him to sleep until about 6.30. Thank you all in advance.
