Darcy started rolling around 6 weeks and by rolling that meant the cradle rocked and she rolled further and banged into the side. So we just put her in the cot. It didn't fit in our room so the decision to move her to her own room was kind of made for us. I didn't really find a benefit with the rocking motion and it was definatley longer but not really wider than a bassinette IYKWIM? We've ditched the cradle and are getting a bassinette for the next one.
