I was so afraid to transition our four-month-old daughter out of her swaddle because she was sleeping at night in a swing and fully swaddled. Our pediatrician recommended getting her use to not being swaddled first before putting her in the crib. I had tried putting her arms out of the swaddle freely while she was still wrapped and it ended disastrously. So, I started researching other options that would be easier on her, and I saw an advertisement for the Zipadee-Zip. Wow! What a great product and the perfect solution for our little girl! I put her in it for a nap and it was like she never slept in anything else! She loved that she could still get to her hands and rub her face! She's now sleeping in her crib at night and napping in her Zipadee-Zip. Thank you for creating a product that gives us peace of mind and a good nights sleep!!
