We have recently moved our DS at 2 and 2 months we had tried a couple of times of the last 6 months but he was not ready, he wouldn't go to sleep even with us in there and if we went to leave he would scream and cry. This time no problems at all. We made sure that the cot was taken down and removed from the room so there was no "safe" option for him and have the safety rail on the bed. We also bought him Bob the Builder doona set, night light and some new books that he choose.
