Thank you for viewing. This is a LOVE TO DREAM Swaddle Up Lite. I am selling it because my child has outgrown it. I used it from newborn to around 3 months old. I bought two because I used them every day, and this is one of them. My child was born in November. During the newborn period, we spent most of our time indoors, and we regulated the temperature with air conditioning. The Lite type, which is thinner than the regular fabric, was perfect. Although it may vary from person to person, it was very helpful. I recommend starting this from the beginning, as it can also lead to sleep training.
