A wrap is a long piece of stretchy or woven fabric which is wrapped around the wearer's body creating a pocket for the baby to sit. 

fabrics
A stretchy wrap is great for a younger/lighter baby or for a toddler who wants to be picked up for short periods.  A woven wrap has less give to it and is more comfortable for extended wear with a heavier baby or toddler. 

why choose a wrap
A wrap is a very versatile carrier that can be used from newborn through toddlerhood.  There are many different types of carries that can be done with a wrap.  A wrap is a head turner!  Everyone will be interested in what it is you are wearing your baby in!  Wraps are extremely comfortable since it distributes the baby's weight across both shoulders and baby can be popped in and out easily.
