Depending upon the types of blankets they are and how big they are, there are plenty of other things you can do with your baby blankets besides wrapping up the baby to stay warm. You are going to want to keep you baby comfortable at all times. Whether they are lying on the floor, in bed or when you have them traveling in the car. Baby blankets can be put down to serve as an extra bit of cushion between their delicate skin and any of these other surfaces.
As the baby blankets get older and worn, you can start to use them for a variety of things as well. They can be used as a changing pad or even a burping cloth. There is no need to mess up a brand new blanket when you have something around that has seen better day.
