How long can my baby wear Baby Merlin's Magic Dream Sack and Dream Sack Walker?

For the majority of babies the ideal time to stop using Baby Merlin's Magic Dream Sack is when they want or need more freedom of movement and are old enough to be transitioned from a crib to a big bed. This is usually when they are ready to sleep without a wearable blanket. There is no set age or developmental stage that makes this transition necessary.
