I have bought a Babyhawk mei tai for my newborn and she is loving it and it has really solved our "what to do with a clingy baby problem". However, yesterday I had her in it for nearly three hours because she was fast asleep, while I did stuff around the house. When I took her out I noticed that her legs were really white, like the circulation had been cut off, and there were significant marks from the indentations of the material on the skin. This all retuned to normal with 10 minutes, but I'm just wondering if it's doing harm? I tend to pull it quite tight to make her and me feel secure. Am I doing it too tight? Was she in it for too long?
