The Rockit was designed and tested for pushchairs and prams. A helping hand when you are out and about. Rockit was extensively safety tested by Intertek, a global product testing company and they felt that it might be mounted by a tired parent on a bar inside the cot, where the baby could snag clothing. Because we want to adhere to the highest safety standard for all our products we're not able to recommend use on cots, cribs or Moses baskets.
