My 6 week old will only sleep in the sling day or night. I have tried everything dark room Ewan the dream sheep won't sleep in pram or swing or cot at all cant get her to go asleep in there and can't transfer her either. I don't know what to do I have tried transferring her at 40 mins but she just wakes up every single time. we have tried getting her to sleep in the cot and pram she will close her eyes for barely two seconds is content for us to try for up to an hour then goes into hysterics. I don't know what method to use to get her to finally sleep somewhere other than on my chest. In 6 weeks I have tickets to a show and I can't leave her for the 3 hours if she won't sleep anywhere but on me...
