We highly recommend not wrapping your babies in these wearable blankets, which helps middle of the night sleeping. These are designed for teens and adults with its extra-large one-size-fits-all options. Instead, we recommend best sleep sack swaddles, baby sleeping bags, or baby sleeping sacks that are shaped like swaddle blankets and lightly weighted sleep sacks made of soft merino wool, micro fleece, or cotton muslin. All of these do an excellent job of keeping a baby warm. Remember, do not place any loose blankets around your child, even if they are early walkers or do not have a startle reflex.
