My Ds was about 8 weeks old when we moved the bassinet into the babies room during the day to get used to the room. At around 10 weeks I started putting him in his cot during the day and found he had no trouble adjusting ( I thought he would) So we just moved him straight into the cot from then.....he looked so small in there tho!!!

But you get a bit of your life back having your room to yourself and a bit more "US TIME" if you know what I mean!!! If you have a good baby monitor then you will have peace of mind!!!
