Tokyo temperatures are reaching 37 degrees during the day and even the nights don’t seem to cool down… Saving Japan’s electro energy and not using the aircondition means finding clever ideas for the little ones to feel comfortable as well in this heat.

One great idea is this Summer Sleeper. Made of a double layer of gaze, it just coveres the front and back and is open at the sides. Two ribbons each keep it closed. I used this sleeper already last year, when my daughter was just 12 months old.
