Query: Miracle Blanket

These blankets are an absolute life safer. I had two for my daughter who is almost 2 now, and I purchased 2 more for my newborn. These blankets keep the baby from getting their arms out, which is critically for a newborn to keep sleeping. It is also very calming for a newborn to be wrapped up tightly, because it simulates the feeling they had in the uterus. I can't say enough about these blankets. Both of my daughters have slept really well in these blankets.
