Dd2's sleeping has completely gone to pot in the last few weeks, it has never been great but she is now not settling until 11 p.m. and only then if I breastfeed her to sleep lying down and she's waking every 2 hours all night. I think the main problem is that she's overtired as she seldom naps during the day. How can I get her to sleep more during the day? She won't sleep on me or in a sling, she will sleep in her car-seat but only whilst the car is moving, she won't sleep in her pram. I've tried putting her in her cot and doing pu/pd or leaving her to whinge for a while but it quickly progresses to full-on crying and I can't leave her to cry. Really don't know what to try next.
