DD is only 4 weeks old and I know it is normal for her not to want to be put down but I'm losing my mind. Up until a few days ago she was not napping really during the day at all but sleeping well swaddled at night in her co sleeping cot with a bit of white noise (4 hours then feed then 2 then feed then another hour or so waking up around 8). But she was getting super grumpy during the day especially in the evenings as she was knackered!!! I then discovered she'd nap beautifully in the sling and rejoiced! However she now will not sleep at night, last few nights she woke up after 30/45 mins, I fed her for 10/20 mins, she fell asleep and repeat all night! Now I don't mind her napping in the sling but I can't sleep when she sleeps and not sleeping at night at all is killing me. I also can't take her out once she's asleep as she wakes straight back up!
