oi both DS and DD hated being swaddled but both love beoing carried in the sling. I love the moby wrap and we also have a baby bjorn I bought second hand for £8 as DH doesn't like stretchy ones.
Walking around shushing and patting, going for walk in pram or sling, white noise like hairdryer or vacuum cleaner (you can get 8 hrs of vacuum cleaner noise on YouTube) also worked. Failsafe is a drive in the car.
I've also mentioned dummies before and how I used to be anti-dummy but DS really NEEDED to suck and only ever had them for sleep. I credit them with DS being an amazing sleeper now, he can go from hyper to drowsy in seconds and throws himself into the cot at bedtime! We can literally plonk him in the cot and walk away and he'll be aaleep in seconds.
Singing also used to help with DS, sometimes I would sing for an hour +! Recently he has started telling me to shush if I start singing. I don't thinl I'm that bad!
Had 2hrs 40 sleep already tonight so feeling optimistic for a good night. Between boobs at the moment and winding :)
