The transition from crib to bed is more than just a change in sleeping arrangements – it's a major milestone separating infancy from childhood. There's really no set time for leaving the crib, but most children make the move somewhere between the ages of 18 months and 3. If your child has outgrown the crib or is repeatedly trying to climb over the sides, it's time for a bed. Another good reason for the switch is to facilitate bathroom trips once potty training begins. Perhaps the most common motivation is the imminent arrival of a new sibling. Whenever you decide to make the move, providing a bed that's as comforting as it is comfortable will keep your child safe and ease the transition for everyone.
