minibensales1 was in a Moses in our room for a week, then cotbed in his room for 2.5 years, then a single bed.
minibensales2 was in a Moses in our room for one month, then cotbed in her room. She's only 3 months old, so no idea when she'll go into a single bed, but we'll do the same.
Top tip, swaddle in Moses baskets, but don't bother in a cot, or blankets. Sleeppods (little baby sleeping bags) are the way forward. No worries about them coming out from under the blankets, or sliding under them etc.
And to second someone else's comment, a room too hot is far more dangerous than a room too cold (within reason). They'll just cry if the room is too cold.
