The Baby Wear site also has a huge list of patterns.
Not the crafty type? Check out these beautiful slings on Etsy and support a WAHM!

Also, know that infants who are carried 3 extra hours a day cry and fuss 43% LESS than those who aren't worn. It makes sense, babies need and want to be held. They also spend more time in a state of quiet alertness which is when babies learn the most.
Carry your baby for a happier, smarter little pumpkin and enjoy every minute because before you know it, they are going to be 18 months old and running away from you!
