We swaddled our baby until she was 3 and 1/2 months old. She started to squrim out of her blanket and wake up every 2 hours. After one sleepless night, I looked online for a way to swaddle a strong baby and I read about the Miracle Blanket®. She slept for 8 hours the first night we used it, and we’ve noticed a definite difference in her disposition during the day. She is happier and smiles at everyone she encounters on our walks. I wish I had learned about it sooner! I will recommend it to all new moms.
