These are great!
I don't actually use them to swaddle as my baby is 10 months old.
She likes blankies and softs blankets. For the summer, this is perfect. So light! My daughter plays with the tag and the corners a lot like she does with her Cupcake mini blankets and this makes her fall asleep as well.
I also use it on top of the stroller if there is too much sun, and for the stroller as a light blanket in the evening.
