My daughter is about 5 1/2 weeks. I have been going for long walks with her each day, about 4 miles or so. Today is our first day of summer heat- high of 85. I usually wear her, but can do the stroller with the infant car seat attachment.
Should I be worried about her temp regulation in weather like this? I could drive to the bike path which is by the lake, and usually has a nice breeze... Should I not wear her?

Help a cold-climate mama out!
