My DD co-slept from birth and then went straight into the toddler bed no problems at all. She never went in the cot, hated it with a passion. And we don't CC here. Co-sleeping was not working well anymore - we were getting kicked constantly and all suffered bad sleep because of that so we tried the bed and WOW, she loves it. The pillow didn't have my scent on it at all and the transition was great. However, every baby is different. Just letting you all know that there were no issues here, just tried the pillow brand new and she took to it brilliantly.
