Both sets of our daughter’s grandparents have a crib for her in their homes. The cribs take up a ton of space that neither homes have to spare. For soon-to-be grandparents considering a crib, you may want to look into the Stowaway Folding Compact Crib. If you are going to purchase a crib anyway, you should definitely consider this compact and easy to store alternative. When your grandchild isn’t around, the crib folds up and can easily be wheeled into storage.
If your son or daughter already has Pack and Play, you may want to consider bypassing the spare crib altogether. We use our Pack and Play as a crib for our daughter whenever we are traveling to a destination that is without a crib.
