I purchased this blanket after many moms mentioned it to me. I am a second time mom and a New Yorker so it takes a lot to impress me. Elijah was only sleeping 2 hours at a time at 2 months old. One night at 4am, I caved in and bought the blanket. It arrived at my home 2 days later and I used it that very same night. That night Elijah went from sleeping 2 hours to 5!!! I used the blanket until he was 3 months old. [At that point] he was too big for it and started to kick out of it. I have sinced given my blanket to another expecting parent and I will purchase 2 more blankets for friends of mine who are expecting.This is the one MUST have for babies that actually works. My only disappointment is that they don’t make them in bigger sizes.
