My ten week old only wants to sleep being held. After feeding he will only fall asleep in my arms, then however carefully I transfer him to his Moses basket he wakes up - either straight away or after ten minutes or so. I've tried putting a hot water bottle in his bed to warm it and swaddling. Any other tips? I really don't want to co-sleep but at the moment it's the only way he will sleep for longer than an hour at a time!
