Keeping in perspective that most of these blankets are light, they will help keep the baby warm and cozy without causing any discomfort. It is also widely known how babies are very sensitive to the weather. The slightest chill can cause an upset stomach. This is just one of the reasons these blankets are so important.
When you are giving a blanket as a gift you are giving a multi-purpose gift that may even help the parent get a little quiet! You can use the swaddling method with a blanket to keep a baby snug and relaxed. As long as a baby is comfortable they will be much less fussy.
Swaddling helps keep a baby safe and will also help keep the baby asleep for longer stretches at a time. When babies are left to sleep freely, they can startle very easily. When startled, most of the time a baby will wake up breaking their sleep. Not only is their sleep interrupted but their parent's sleep will most likely be interrupted as well.
These blankets serve a practical purpose, but they can also have a sentimental value as well. You child may not know the important of their blanket now, but when kept as a keepsake for them it can serve as a special symbol of your love and their infancy. This is a gift they may very well hold on to as they grow older because of its sentimental value.
