Sorry noelle that you are feeling so bad, I seriously think chronic, long term sleep deprivation has made me see things on another level that I never understood before. I hope someone in the toddler section can give you some good advice.
Seaweed eater, interesting what you ask about Dad getting her to sleep. It caused me to just have a lightbulb moment! Previously I used to be able to get S down at bedtime like clockwork between 6.30-7pm. I came on here as she wouldn't nap. Now I can get 3 naps, mostly short ones of 30-50 minutes long, but I'll take that thank you very much! I can get her to sleep for those in 10 minutes. The problem now has changed to bedtime! No matter what I do, however fast and prompt, so not to over stimulate her, nothing works. The magical booby does nothing! I can rock her for ages and as soon as I out her down she screams. However for naps I rock her, put her down, she whimpers a little then I place my hand on her belly and off she goes to sleep! Anyway my lightbulb moment is as she is almost 6 months, clearly very aware of a lot now, I was wondering if she is holding out for dad to put her to bed, as he can do it no problem, where a few weeks ago, it was only me! I shall have to see what she's like on his days off. When he's at work if she goes to bed at 7 pm she won't see him at all. Hmmmm what do you think? Is it possible that babies can do that at her age??
Leids, I co sleep and OH is in the other room. I have started the transition to crib as I think it'll help my sleep to get back into my own bed and may help Sophia's. I have started using the cot for naps during the day, the next stage will be to get her to start the night in her cot, but as you can see that bit may have to wait as bedtimes are now a problem. But after that I would probably part time co sleep to start with, so cot and then if needed when she wakes would co sleep for half the night. When do you move house? How long do you have. I totally get why you don't want your baby in with your OH, I don't either at the moment but would consider it in future with a large bed if S really won't sleep the night in the cot.
