Unbeknownst to kids, their parents do not have eyes in the back of their head. Need somewhere safe yet roomy to pop your little one and their mass collection of toys, books and even another little pal? A play pen is your answer. Indoor or outdoor play pens are available these days so you can keep toys and books close to baby while letting them roam around in a spacious but enclosed environment. Take your outdoor play pen with you to a park, on day trips or holidays so your baby can enjoy the fresh air and sunshine while remaining occupied and close by.
