When should my baby transition from Baby Merlin's Magic Dream Sack to the Dream Sack Walker?

We recommend staying in the Small Baby Merlin's Magic Dream Sack until your little one exceeds the weight range. It is recommended that babies stay in Baby Merlin's Magic Dream Sack as opposed to the Large Dream Sack Walker during that age range so that it is not easy for them climb out of the crib. Once babies are old enough to have more mobility they can be transitioned to the Large Dream Sack Walker with foot openings.
