My first child was born during an uncharacteristically hot June. During her first months, our main goal was to keep her covered, but yet keep her cool enough during naps and at nighttime. As for my son, he was born at the very end of September and the goal was just the opposite as we struggled to keep him warm during the day and at night.
Ironically, the same product that would have worked for my June baby would have also been the one that I would recommend for my September baby. This, my friends, is the brilliance of Merino wool, a natural body temperature regulator that helps keeps your baby cool during hot weather and warm during cold weather. 100% natural, itch-free and allergy-safe, Merino wool captures and circulates air to insulate your child when the room temperature falls, but also releases excess body heat and moisture as the room temperature rises. This means your baby stays warm and dry without overheating.
