I have a newly pregnant friend and I have been raving to her about babywearing. I have slung all 3 of my boys. She lives in Tybee Island, GA and is wondering if slings would be too hot for the baby. I told her that even in IL it gets hot in the summer and it has never been an issue for me. I told her that babies are carried in slings in Africa/South America/Tropical Regions. It is a question I never gave much thought to.... but I don't live on an island off the coast of GA. Any specific recommendations on fabric or carrier? I have been talking to her about maya wraps and native pouches because they are primarily what I use and am most familiar with.
