I have been co-sleeping with ds for a couple of weeks as I found it easier for all of us (am bf'ing, he still feeds two hourly at seven weeks). But as our bed is not king size I would like to sleep comfortably with dh in one bed again, so decided its time to move ds into his crib. His crib is right next to our bed but even if I put him down asleep he would wake up 5mins later screaming. it then gets very hard to put him down again, let alone to make him fall asleep while in crib (it's a rocking cradle, rocking doesn't help, holding his hand, singing, whispering, etc also tried).
Is there anything that could be done to get him to sleep in his crib? I don't mind to get up every two hours to feed him (I don't expect him to sleep through this early). DH suggests controlled crying, but I find that unbearable.
