DD2 is 13 wks and over the last 2-3 weeks has gone from waking once or twice a night to waking every 2 hours, sometimes more often. Yesterday I put her down at 8, she was awake at 9.30, 12.20, 2, 4, 5 and 6 and hasn't slept since then. She clearly isn't hungry all those times, although in my addled state I have been feeding her back to sleep. But it's getting worse and I need to sort it out. Don't really want to cc, and it's not an option as DD1 needs to sleep. What can I do to help her to self settle? She is in a cot next to the bed and DH is in the spare room getting a solid 8 hours kip. She has four or five naps a day of about half an hour, but as DD1 is on holiday at the moment I can't sleep then.
