For the last week or so my 11mo DD's sleep has gone haywire. She still self settles fine for naps and at the start of the night, but wakes after 2 hours and from that point will not go back to sleep in her cot. I'm having to sit with her all night on the rocking chair in her room, breastfeeding her almost constantly (just comfort suckling mostly - she eats really well in the day and was down to BFing only once or twice at night before this). If I put her down in her cot, she just sits / stands up and cries. If I wait until she's deeply asleep, she either wakes right away and sits / stands, or wakes after 10 minutes or so. (Which is the worst, as I've usually just got into bed!) DH doesn't do wakes from 12-6 for a variety of reasons I won't go into here. I work on a Monday and Tuesday and am dreading going to work again this week on effectively no sleep. DD is so tired too, she's not her usual happy self in the day. I'm feeling pretty desperate and open to any advice at this point.
