Hi, mommy experts! I'm planning ahead for a newborn in the summer and would like to have a secure, comfortable wrap or sling to use outdoors--lots of bending and digging-- in sometimes very hot weather. I understand sling styles can be a bit uncomfortable with lots of movement, and the body-wrap style can be hot. Anyone got some proven and tried wrap ideas for this? I already have a maya on the way for wandering around gently-like.
