Receiving Blankets are perfect for swaddling, cuddling, play time and belly time. They can also be used as nursing or stroller covers. Make sure you buy those sized at 30X30 or larger, as your baby will grow FAST.
If you are going to buy them in store, make sure they are soft and made from cotton instead of synthetic fibers. If you buy online (link), check user reviews before you buy.
You probably will need about 5 to 10 receiving blankets for your kid. If you receive more than ten from your friend, it is a good idea to exchange the extra ones for other items you need.
Tips: when your kid doesn’t need receiving blankets for swaddling any more, don’t throw them away. They can be used for other purposes, such as burp clothes.
